4. The Reactis Top-Level Window#

This chapter concentrates on the functionality available in the top-level window when Simulator is turned off, or disabled. Simulator is always disabled when the Reactis top-level window first appears. It may also be explicitly disabled by clicking button (window item 12). Clicking button (window item 13) turns Simulator on. The functionality of the Simulator enabled mode is described in the Reactis Simulator chapter.

4.1. Labeled Window Items#

An annotated screenshot of the Reactis top-level window appears in Figure 4.1. This section describes the functionality of the numbered items.

_images/reactisTopA.png

Fig. 4.1 The Reactis top-level window.#

The following numbers refer to the labeled window items in Figure 4.1.

  1. The model hierarchy panel shows the subsystems in the model and how they are related. See Model Hierarchy Panel.

  2. The main panel displays the currently selected Simulink subsystem, Stateflow diagram, C code, or Embedded MATLAB code. See Main Panel.

  3. Load a new model into Reactis.

  4. Undo an operation (add, edit, remove, move) on a Validator objective. See Reactis Validator for a description of Validator objectives.

  5. Redo last undone operation (add, edit, remove, move) on a Validator objective. See Reactis Validator for a description of Validator objectives.

  6. Zoom in.

  7. Zoom out.

  8. Fit to page.

  9. Go back in the history of displayed subsystems.

  10. Go forward in the history of displayed subsystems.

  11. Display the parent of the currently displayed subsystem.

  1. Disable Reactis Simulator.

  2. Enable Reactis Simulator.

4.3. Model Hierarchy Panel#

The model hierarchy panel (window item 1) shows the subsystems in the model and how they are related. Clicking on a + to the left of an item displays the subsystems of the item, while clicking on a - to the left of an item hides the subsystems. Clicking on the name or icon of an item causes the diagram for the item to be displayed in the main panel (window item 2). Pressing the “F2” key causes the parent of the currently displayed system to be displayed. Hovering in the hierarchy panel over a child of the currently displayed system causes the child to be highlighted in the main panel.

Right-clicking on an item in the hierarchy panel causes a pop-up menu to be displayed with two enabled entries Coverage Tracking and Copy System Path and several disabled entries. The disabled menu items become enabled when Simulator is enabled and are described in the Reactis Simulator chapter.

The Coverage Tracking entry lets you modify how coverage is tracked for the given subsystem. Coverage for a subsystem can either be tracked cumulatively, or disabled altogether. If you disable coverage tracking for a subsystem, Reactis Tester will not attempt to exercise targets within the subsystem when generating tests and Simulator will not display coverage information for targets in the subsystem. See Excluding a Subsystem for details on disabling coverage tracking. See Cumulative Subsystem Coverage for details on cumulative coverage tracking.

The Copy System Path entry causes the path of the selected subsystem to be copied to the clipboard. When Reactis uncovers an issue in your model, the copied system path can help you easily navigate to the appropriate subsystem in the Simulink editor to resolve the problem. To do so:

  1. In the hierarchy panel, right-click on the subsystem of interest and select Copy System Path

  2. Start MATLAB and open your model in Simulink

  3. At the MATLAB prompt type open_system('

  4. Paste in the system path from the clipboard

  5. Type ') to complete the command. At this point, the command you entered should look something like this: open_system('adaptive_cruise/Controller/ACC Override')

  6. Hit Enter. The subsystem of interest will be displayed in the Simulink editor.

4.4. Reactis Main Panel#

The main panel (window item 2) displays the currently selected Simulink subsystem or Stateflow diagram. C code or EML code may also be displayed in the main panel if you are using Reactis for C Plugin or the Reactis for EML Plugin. You can use the mouse to interact with the diagram in a number of different ways, including hovering over model items, single- or double-clicking on items, and right-clicking in various parts of the panel. Note that some operations in the main panel are only available when Simulator is enabled. See the Reactis Simulator chapter for a description of those operations. The following sections describe mouse operations available when Simulator is disabled.

4.4.1. Hovering#

4.4.4. Right Clicking#

Causes different pop-up menus to be displayed. The contents of the menu vary based on where the click occurs and whether or not Simulator is enabled. A summary of the menu items available when Simulator is disabled follows. For descriptions of the menu entries available when Simulator is enabled, see the Labeled Window Items section.

Right-Click Location

Menu Entries (when Simulator is disabled)

Simulink signals, Simulink blocks, Stateflow variables
Add To Test Points

Add the data item to the list of test points which may be associated with a model, stored in the model’s .rsi file, and viewed from the Reactis Info File Editor. Test points are internal data items (Simulink signals or Stateflow variables) that Reactis subjects to user-specified checks during simulation and test generation. For example, Reactis can be configured to record values for test points in test suites and have Reactis Simulator flag any differences between the values computed by a model for a test point and those stored in a test suite. Additionally, a type constraint can be assigned to a test point and Reactis can be configured to monitor if a test point is ever assigned a value outside the set of expected values specified by the constraint. For more details on test points please see Test Points Pane.

Extract Subsystem…

Extract a subsystem and save it in a separate model file. Selecting this item causes the selected subsystem and any components related to the triggering of the subsystem to be extracted from the model and inserted into a new model. Reactis may then be applied to the newly extracted subsystem. Usage of this feature is described in Extracting Subsystems

Create New Harness…

Create a new test harness for the subsystem in order to test it in isolation (see Test Harness Pane). When you create a harness for a subsystem, its inputs and outputs are treated as top-level inputs and outputs for the purpose of testing the subsystem on its own. When Reactis Tester generates a test suite for a model configured to use a harness, Tester will directly select values for the inputs of the harness subsystem and capture the output values computed by the harness subsystem to store them in the generated test suite. When a model with harness is run in Reactis Simulator, coverage and data values can be tracked in the harness subsystem, while other parts of the model are grayed out (and not executed).

Model Reference block
Open Model

Load the referenced model in a separate Reactis window and using the referenced model’s .rsi file.

4.4.5. Dragging the Mouse#

When a diagram is too big to display completely in the main panel, scroll bars appear for repositioning the diagram. Alternatively the diagram may be repositioned by left-clicking and dragging in the panel or by using the cursor keys. If your mouse includes a scroll wheel, then you may scroll vertically by clicking in the main panel and then using the scroll wheel.

Left-clicking and dragging in the panel while holding down the control key defines a print region that can be used for printing parts of a model. The print region is represented as a shaded blue box; it may be removed using the File > Remove Print Region menu entry or pressing the escape key.

4.4.6. Keyboard Shortcuts#

Finally, pressing the F2 key within this panel causes the parent of the currently displayed subsystem to be displayed, pressing F3 zooms in, and pressing F4 zooms out.

4.5. Lists of Matching From/Goto or Data Store Blocks#

_images/fromGotoDialog.png

Fig. 4.2 The list of matching From/Goto or Data Store blocks.#

This dialog opens after double-clicking on a From, Goto, Goto Tag Visibility or Data Store Read/Write/Memory block in Reactis. It lists all other such blocks in your model that match the double-clicked block.

In this dialog you can:

  • Double-click on a row to have Reactis highlight the block in the main panel. If the block is located in a different subsystem than the one currently displayed, Reactis will switch to that subsystem.

  • Click on a column header to re-sort the table by the values of that column.

  • Click on the Close button to close the dialog.

4.6. Configuration Variable Panel#

If you have defined configuration variables for your model (see Configuration Variables Pane), Reactis will include an entry Configuration Variables in the top-level of the hierarchy panel. Clicking on this entry displays a list in the main panel containing and entry for each currently defined configuration variable. This panel allows you to view and manipulate configuration-variable information.

Double-clicking on a configuration variable when Simulator is disabled opens the type editor dialog to specify a constraint for the configuration variable. When Simulator is enabled and at the start of a simulation run (no steps have been taken), double-clicking on the configuration variable opens a dialog to specify a value for the variable.

When Coverage > Show Details is selected in Simulator, information on boundary value coverage for configuration variables is conveyed in the panel. A block is highlighted in red if it has any uncovered boundary value targets. See Boundary Values for Inports, Test Points, and Configuration Variables for a description of the boundary value targets associated with a configuration variable. Hovering over the variable in this panel when Simulator is enabled displays test and step in which exercised targets were covered.

4.7. Extracting Subsystems#

Note

The Test Harness mechanism now supported by Reactis is usually the easier and more robust way to achieve what was previously done with Extract Subsystem.

It is sometimes useful to apply Reactis to individual subsystems within a larger model. For example, if a given model is closed-loop, with a controller connected to a plant, then isolating the controller subsystem may be needed in order to generate tests for the controller. In other cases, very large models might require subsystem-at-a-time analysis. Reactis enables such analysis by providing a facility to extract subsystems from models. This feature isolates a subsystem, optionally along with portions of the model involved in triggering the subsystem, and stores the result as a new model in a separate .slx file.

When extracting a subsystem, Reactis retains the hierarchical structure of the original model. That is, the original subsystem interfaces enclosing the extracted subsystem are retained, although the input and output ports connected to these interfaces are altered to coincide with those of the extracted subsystems. Retaining the model hierarchy in this fashion facilitates the inclusion of triggering mechanisms and Data Store Memory blocks in the extracted model.

_images/extractSubsystem.png

Fig. 4.3 The Extract Subsystem dialog.#

The subsystem extraction utility is invoked by loading a model into Reactis, then right-clicking on the Simulink subsystem or Stateflow chart to be extracted and selecting the Extract Subsystem entry in the pop-up menu. This causes the Extract Subsystem dialog shown in Figure 4.3 to appear. Using the dialog you can specify the name of the file in which to store the extracted model and whether the triggering mechanism should be included.

The Port settings section lets you specify if information (type and sample rate) from the original model should be propagated to the top-level ports of the extracted subsystem. Note that when this information is not propagated, the types and sample rates inferred for the ports of the extracted subsystem may differ from those inferred in the original model (since type and sample rate information has been removed in the extracted model). When the propagation is enabled, for each port P of the subsystem being extracted, the extraction routine:

  1. Traces the signal connected to P up one level in the hierarchy to a port P’

  2. Records the type/rate inferred for P’ in the original model

  3. Explicitly sets the type/rate for P’ in the extracted model

The following limitations apply:

  • If the type of P’ is a virtual bus then the type will not propagate.

  • If P’ has multiple sample rates or is triggered by an irregular mechanism such as a Stateflow chart then the sample rate will not propagate.

When you click Extract, Reactis will extract the subsystem, save it under its new name, open a new Reactis window, and load the extracted model. Note that the extracted subsystem is saved as a standard .slx file, making it easy to edit the extracted model using Simulink if changes to new model are necessary.

If you select Extract subsystem and triggering mechanism then portions of the original model outside the subsystem of interest, but involved in the triggering of that subsystem will be included in the extracted model. More precisely, if the extracted subsystem

  • is a triggered subsystem,

  • is located within a triggered subsystem, or

  • contains one or more triggered subsystems whose triggers are connected to something outside the extracted subsystem

then Reactis determines which portions of the model residing outside of the extracted subsystem should be retained in order to trigger the extracted subsystem properly. This ensures that the simulation times during which the extracted subsystem is executed match those of the subsystem before it was extracted.

If the extracted subsystem references Data Store Memory blocks located outside the extracted subsystem, Reactis will keep those Data Store Memory blocks. However, Reactis will not keep any Data Store Write blocks outside the extracted subsystem.

Note that the extraction tool can extract parts of a model even if Reactis reports errors when trying to run it. This enables Reactis to be used on models that contain Simulink features that are unsupported by Reactis, as long as those features are not used in the extracted subsystem. For example, one may extract a discrete-time controller subsystem from a model that includes a continuous-time plant.

4.8. Unpacking Top-Level Buses#

If a model has bus inputs at the top level, this feature lets you generate a wrapper model that has no bus inputs, but has scalar inputs that feed into Bus Creator blocks that construct buses suitable for input to the original model which is referenced by a Model Reference block. The operation can be invoked by right-clicking in white space at the top level of the model and selecting Unpack Bus Inports to open the dialog shown in Figure 4.4. The generated wrapper model will be stored in a new .slx file named in the entry box of the dialog. Two checkboxes let you configure how the wrapper model is generated:

Stub unused elements in top-level inport buses

When checked, if an element of a bus is unused, no input port will be created for that element. Instead, the signal for that element will be connected to a Ground block.

Hide stubbed elements in wrapper subsystem

When checked, create a wrapper subsystem around the Inport/Ground blocks so that the top-level system looks cleaner (since it contains only the scalar input ports and not the stubbed signals).

_images/unpackBusInports.png

Fig. 4.4 The dialog to unpack top-level buses into scalar inputs.#

4.9. Printing Models#

Reactis includes a facility for printing models. The print dialog shown in Figure 4.5 appears when you select File > Print….

The radio buttons and check-boxes in the Print Range section of the dialog specify which portions of the model should be printed as follows.

Selection.

Prints only the portion of the model located within the current print region in the main panel. If no print region is defined, this entry is disabled. A print region is selected by left-clicking and dragging in the main panel while holding down the control key. The print region is cleared by selecting menu item File > Remove Print Region.

Current system.

Prints only the system currently displayed in the main panel.

Current system and above.

Prints the system currently displayed in the main panel and all systems between the current system and the top-level system of the model. Each such system is printed on a separate sheet of paper.

Current system and below.

Prints the system currently displayed together with all its subsystems, sub-subsystems, etc. Each system is printed on a separate sheet of paper.

Whole model.

Prints the whole model.

Expand unique library links.

When checked, library blocks referenced by the model will be printed. Note that each library block is printed only once, even though some blocks might be referenced multiple times by a model.

Look under masks.

When checked, masked subsystems will be printed.

The following radio buttons and check-boxes in the Frame section specify whether a frame should be printed on each page, and if so what content should be included in the frame.

No frame.

When selected, no frame is printed.

Frame.

When selected, a frame is printed.

Include system name.

When checked, the name of the system is printed in the upper left part of the page frame.

Include print date.

When checked, the date the model was printed is included in the bottom left corner of the frame on each page.

Include page number

When checked, the page number is printed in the bottom right corner of the frame on each page.

Include file name.

When checked, the name of the .slx file containing the model and the folder containing the file is printed in the bottom left corner of each page.

The remaining buttons in the print dialog work as follows.

Help.

Display print dialog help.

Page Setup…

Invokes a dialog that allows the user to specify paper size and margins, and whether printing should be portrait or landscape.

Preview.

Open a viewer to display what will be printed.

Print…

Begin printing.

Close.

Close the dialog (and cancel printing).

4.10. Reactis Global Settings#

Selecting File > Global Settings… invokes the Reactis Global Settings dialog, which allows you to adjust the behavior of Reactis. The global settings are partitioned into seven tabbed panes each described in detail below: General, Reactis for C, Reactis for EML, MATLAB, Path, Files, User Info, and License.

4.10.1. General Global Settings#

The General global settings pane shown in Figure 4.6 includes the following items.

_images/globalSettingsGeneralB.png

Fig. 4.6 The Global Settings dialog with the General pane selected.#

GUI Language.

Language used in the Reactis GUI.

Allow connections between Reactis and Reactis for C.

If enabled, Reactis will a. listen for and respond to incoming link connections from Reactis for C and b. Show the File > Invoke Reactis for C menu item to start and link to Reactis for C. See the Linking with Reactis for C chapter for more information on this functionality.

Invoke Reactis for C version.

This drop-down box lists installed versions of Reactis for C that support linking. The selected version will be invoked when the user selects File > Invoke Reactis for C. See the Invoking Reactis for C from Reactis for Simulink section for more information.

Automatically check for updates (once a day).

Instructs Reactis to check once per day whether updates to Reactis are available for download. If updates are found you will be asked if you would like to download and install the patch. Note: this feature can be disabled at install time; in which case this checkbox will not appear in the dialog.

Enable logging.

Enable logging, specify a log level, and indicate the file to which the log should be written. Note that logging degrades performance and can create very large log files; therefore, it is typically only used to diagnose problems. The log level string will be provided by the Reactis support team if you are asked to create a log file.

4.10.2. Reactis for C Global Settings#

This pane is used to enable and configure the Reactis for C Plugin.

4.10.3. Reactis for EML Global Settings#

This pane is used to enable and configure the Reactis for EML Plugin.

4.10.4. MATLAB Global Settings#

Reactis invokes MATLAB when importing a model for simulation, test-generation, and validation. The MATLAB global settings pane, shown in Figure 4.7, enables you to configure some aspects of how Reactis invokes MATLAB.

_images/settingsMATLAB.png

Fig. 4.7 The Global Settings dialog with the MATLAB pane selected.#

Use MATLAB version.

If you have multiple versions of MATLAB installed, this pull-down menu may be used to specify the version of MATLAB that Reactis will invoke. Each installation of MATLAB that Reactis automatically detects will have an entry in the menu. The menu includes two additional entries:

None specified (use Windows path)

When this entry is selected, Reactis will invoke the version of MATLAB that appears first in the Windows path.

Custom

When this entry is selected, Reactis will invoke the version of MATLAB that appears in the MATLAB root text entry box (just below this menu in the MATLAB pane of the global settings dialog).

Use MATLAB root.

This text entry box becomes enabled when the Custom entry of the MATLAB version menu is selected. By entering a folder name (directly or by clicking the button to the right and using the file-selection dialog), you specify a folder containing the MATLAB installation which Reactis should use. This configuration is typically only used for a custom MATLAB installation that Reactis is unable to detect automatically.

Invoke MATLAB via:

MATLAB supports several different mechanisms for third party applications to invoke it. Each method has advantages and disadvantages. This menu lets you configure which mechanism will be used by Reactis to invoke MATLAB. The options are:

MATLAB engine interface via C API

This option works with older versions of MATLAB, but requires administrator privileges to switch between MATLAB versions.

Windows COM interface

This option does not require administrator privileges to switch between MATLAB versions, but: does not work with R2006b or earlier, is partially compatible with R2007b through R2011b (you can switch between only one MATLAB installation in this range and newer versions), is fully compatible with R2012a and later.

Full MATLAB window

This option will start a full MATLAB session to communicate with. It is a useful option if other methods of invoking MATLAB fail but will require more time for MATLAB to start up.

Full MATLAB window (hidden)

Similar to the previous option but hides the MATLAB window it is communicating with. This is less distracting but for some models MATLAB will not work properly if the window is hidden.

MATLAB start up timeout (seconds).

When Reactis invokes MATLAB, it will wait this long for a response indicating a successful invocation before assuming that MATLAB will not start properly. This setting is unavailable when using the Windows COM interface.

Keep MATLAB running after Reactis disconnects.

When Reactis invokes MATLAB, it will use this option to determine whether to leave the MATLAB instance running so that there is no need to wait for a new MATLAB session to start when Reactis uses MATLAB subsequently. This is useful in certain scenarios, for example, when using Reactis on a model while making frequent changes to the model in Simulink, or running Reactis on a large number of models either in the GUI or via the API. The MATLAB instance that is left running will close itself if Reactis has not used it for a period of time. This timeout period is specified in seconds. The option to leave the MATLAB instance running is not available if MATLAB is invoked via “MATLAB engine interface via C API” or “Windows COM interface”. In those cases Reactis always closes the MATLAB instance after it has been used.

4.10.5. Path Global Settings#

The Path pane of the Global Settings dialog, shown in Figure 4.8, enables you to specify the list of folders in which Reactis will search for files such as Simulink model libraries (.slx), MATLAB scripts (.m), and S-Functions (.dll, .mexw32, .m). The order in which folders are listed in the dialog specifies the search order (from top to bottom).

Note that Reactis also gives users the capability to define model-specific search paths which consist of a list of folders to be searched when loading a given model. The model-specific path is set using the Reactis Info File Editor. When searching for files, the complete search path is constructed by prepending the model-specific path to the global path.

_images/settingsPathA.png

Fig. 4.8 The Global Settings dialog with the Path pane selected.#

The buttons labeled in the figure work as follows.

  1. Add a new folder to the list.

  2. Open a dialog to edit the currently selected folder.

  3. Remove the currently selected folder(s) from the list.

  4. Select all folders in the list.

  5. Copy the currently selected folder(s) to the clipboard.

  6. Paste from the clipboard to the list.

  7. Invoke MATLAB, query the MATLAB path, and add each folder in the MATLAB path to the list.

  8. Move the currently selected folder up one spot in the list.

  9. Move the currently selected folder down one spot in the list.

  10. Move the currently selected folder to the top of the list.

  11. Move the currently selected folder to the bottom of the list.

  12. Produce warning if multiple instances of a library are found in the search path.

4.10.6. Files Global Settings#

The Files pane, shown in Figure 4.9, lets you specify the folder where Reactis should store files that it creates. These files include Reactis Info (.rsi), Reactis Profile (.rsp), and Reactis Cache (.mwi) files. The setting also determines the default location (which you can override) for Reactis test suite (.rst) and coverage report (.html) files.

If you choose to specify a subfolder, then the folder name entered in the textbox is relative to the model folder. The special string %MODELNAME% may be included in the subfolder name and will be replaced by the base name of the model file.

For example, for a model cruise.slx located in a folder c:\models, a subfolder string of reactis\%MODELNAME% will cause the files associated with cruise.slx to be stored in

c:\models\reactis\cruise.

_images/settingsFiles.png

Fig. 4.9 The Files pane of the Global Settings dialog lets you specify the folder where Reactis should store any files that it creates.#

4.10.7. User Info Global Settings#

The User Info pane is shown in Figure 4.10. When Reactis is configured to use a remote license server as described in the next section, information contained in this panel is submitted to the server when Reactis is started, and available to all users who have access to the server.

The list of users occupying licenses at a given time may be obtained using the License pane of the Global Settings dialog as described below, or using the standalone License Monitor utility included in the Reactis License Manager distribution. This utility may be invoked from the Windows Start menu.

_images/settingsUser.png

Fig. 4.10 The Global Settings dialog with the User Info pane selected.#

4.10.8. License Global Settings#

The License pane, shown in Figure 4.11, enables you to query and specify license configuration information. The first two sections display the MAC address of the machine on which Reactis is running and the location of a local license file if one is in use.

The third section of the pane displays a list of servers running the Reactis License Manager. When Reactis is invoked, this list will be searched from top to bottom for an available license. The lowest portion of the pane displays a list of users currently using licenses for the License Manager/product currently selected in the License servers list.

_images/settingsLicenseA.png

4.11. Default Model-Specific Settings#

The Default Model-Specific Settings dialog lets you specify default settings to be used when creating a new .rsi file. Whenever a new .rsi file is created, these settings are used in the new .rsi file. Subsequently, the settings for the model are modified using the Info File Editor. The dialog includes the following panes:

General

various settings primarily related to how a model executes (e.g. conditional input branch execution, short circuiting, etc.)

Error Checking

what types of errors should be flagged (overflows, NaN values, etc.)

Coverage Metrics

settings that specify which coverage metrics are used for a model and how the coverage metrics are configured (e.g. multi-block versus traditional MC/DC).

C Code

settings to configure the Reactis for C Plugin.

The Reactis Info File editor includes a pane corresponding to each of the above four panes. For a description of each setting see the Reactis Info File Editor chapter.
