Description

[polyspaceFolder, resultsFolder] = pslinkrunCrossRelease(ModelOrSubsystem) runs a Polyspace® analysis of the code generated from ModelOrSubsystem by using Embedded Coder® from an earlier release of Simulink®.

example

[polyspaceFolder, resultsFolder] = pslinkrunCrossRelease(ModelOrSubsystem,psOpt) runs a Polyspace analysis of the code generated from ModelOrSubsystem through an earlier release of Simulink. The analysis uses the model configuration options that are specified in the pslinkoptions object psOpt.

example

[polyspaceFolder, resultsFolder] = pslinkrunCrossRelease(ModelOrSubsystem,psOpt,asModelRef) runs a Polyspace analysis of the code generated as a model reference from ModelOrSubsystem through an earlier release of Simulink.The analysis uses asModelRef to specify which type of generated code to analyze—standalone code or model reference code.

example

[polyspaceFolder, resultsFolder] = pslinkrunCrossRelease(ModelOrSubsystem,psOpt,asModelRef,OptionsFile) runs a Polyspace analysis of the code generated from ModelOrSubsystem through an earlier release of Simulink. The analysis uses the Polyspace analysis options specified in the options file OptionsFile.

To run a Polyspace analysis on code generated by using an earlier release of Simulink, use the function pslinkrunCrossRelease. The analysis uses the configuration options associated with ModelOrSubsystem. The Simulink release must be R2020b or later. Before you run an analysis, you must integrate Polyspace with Simulink. See MATLAB Release Earlier Than Polyspace.

  1. Open the Simulink model polyspace_controller_demo and configure the model for code generation.

    cd(matlabroot);
mdlName = 'polyspace_controller_demo';
openExample('polyspace_code_prover/OpenSimulinkModelForPolyspaceAnalysisExample', ...
'supportingFile',mdlName);
mkdir TempDir;
load_system(mdlName);
cd TempDir;
configSet = getActiveConfigSet(model);
set_param(configSet,'Solver','FixedStepDiscrete');
set_param(configSet, 'SystemTargetFile', 'ert.tlc');

  2. To enable packing the generated code in an archive, set the option PackageGeneratedCodeAndArtifacts to true.

    set_param(configSet, 'PackageGeneratedCodeAndArtifacts', true)

  3. Generate code from the model.

    slbuild(model);

  4. Start a Polyspace analysis.

    % Run Polyspace analysis
[~,resultsFolder] = pslinkrunCrossRelease(model);
bdclose(model);
    The character vector resultsFolder contains the full path to the results folder.

To run a Polyspace analysis with modified model configurations, use a pslinkoptions object. For a list of model configurations related to Polyspace analysis that you can modify, see the table Polyspace Configuration Parameters Supported by pslinkrunCrossRelease on this page. Before you run an analysis, you must integrate Polyspace with Simulink. See MATLAB Release Earlier Than Polyspace.

  1. Open the Simulink model polyspace_controller_demo and configure the model for code generation.

    cd(matlabroot);
mdlName = 'polyspace_controller_demo';
openExample('polyspace_code_prover/OpenSimulinkModelForPolyspaceAnalysisExample', ...
'supportingFile',mdlName);
mkdir TempDir;
load_system(mdlName);
cd TempDir;
configSet = getActiveConfigSet(model);
set_param(configSet,'Solver','FixedStepDiscrete');
set_param(configSet, 'SystemTargetFile', 'ert.tlc');

  2. To enable packing the generated code in an archive, set the option PackageGeneratedCodeAndArtifacts to true.

    set_param(configSet, 'PackageGeneratedCodeAndArtifacts', true)

  3. Generate code from the model.

    slbuild(model);

  4. To specify the model configurations for the Polyspace analysis, use a pslinkoptions object. Create this object by using the function pslinkoptions. To run a Bug Finder analysis, set psOpt.VerificationMode to 'BugFinder'. To assert the range defined in a block on its input variables, specify psOpts.InputRangeMode as 'DesignMinMax'.

    % Create a Polyspace options object from the model. 
psOpts = pslinkoptions(model);

% Set model configurtion for the Polyspace analysis.
psOpts.VerificationMode = 'BugFinder';
psOpts.InputRangeMode = 'DesignMinMax';

  5. Start a Polyspace analysis. To specify model configuration for the Polyspace analysis, set the object psOpt as the optional second argument in pslinkrunCrossRelease.

    % Run Polyspace analysis
[~,resultsFolder] = pslinkrunCrossRelease(model,psOpt);
bdclose(model);
    The character vector resultsFolder contains the full path to the results folder.

To accelerate model simulations, invoke referenced Simulink models as simulation targets. To generate model reference simulation targets from a Simulink model, generate code from the ModelOrSubsystem by using slbuild with the build process specified as ModelReferenceCoderTarget. Package the generated code by using packNGo (Embedded Coder). Then, analyze the generated code by running a cross-release Polyspace analysis. Before you run an analysis, you must integrate Polyspace with Simulink. See MATLAB Release Earlier Than Polyspace.

  1. Open the Simulink model polyspace_controller_demo and configure the model for code generation.

    cd(matlabroot);
mdlName = 'polyspace_controller_demo';
openExample('polyspace_code_prover/OpenSimulinkModelForPolyspaceAnalysisExample', ...
'supportingFile',mdlName);
mkdir TempDir;
load_system(mdlName);
cd TempDir;
configSet = getActiveConfigSet(model);
set_param(configSet,'Solver','FixedStepDiscrete');
set_param(configSet, 'SystemTargetFile', 'ert.tlc');
set_param(configSet, 'PackageGeneratedCodeAndArtifacts', true)

  2. Generate code from the model. Specify the option ModelReferenceCoderTarget. See slbuild (Simulink).

    slbuild(model,'ModelReferenceCoderTarget');
    The generated code is stored in the folder slprj

  3. To package the code that is generated as a model reference, use the function packNGo. Locate the file buildinfo.mat in <working folder>/slprj/ert/polyspace_controller_demo and use the full path to it as the input to packNGo. This command generates an archive containing the generated code and the object buildinfo.mat. See packNGo (Embedded Coder).

    % Locate buildinfo and generate code archive
buildinfo = fullfile(pwd,'slprj','ert',model,'buildinfo.mat');
packNGo(buildinfo)

  4. To specify the Polyspace analysis options, use a pslinkoptions object. Create this object by using the function pslinkoptions. To run a Bug Finder analysis, set psOpt.VerificationMode to 'BugFinder'.

    % Create a Polyspace options object from the model. 
psOpts = pslinkoptions(model);

% Set properties that define the Polyspace analysis.
psOpts.VerificationMode = 'BugFinder';
psOpts.InputRangeMode = 'DesignMinMax';

  5. Start a Polyspace analysis. To specify Polyspace analysis options, set the object psOpt as the optional second argument in pslinkrunCrossRelease. To analyze the code as a model reference, set the optional third argument asModelRef to true.

    % Run Polyspace analysis
[~,resultsFolder] = pslinkrunCrossRelease(model,psOpt,true);
bdclose(model);
    The character vector resultsFolder contains the full path to the results folder.

  1. Open the Simulink model polyspace_controller_demo and configure the model for code generation.

    cd(matlabroot);
mdlName = 'polyspace_controller_demo';
openExample('polyspace_code_prover/OpenSimulinkModelForPolyspaceAnalysisExample', ...
'supportingFile',mdlName);
mkdir TempDir;
load_system(mdlName);
cd TempDir;
configSet = getActiveConfigSet(model);
set_param(configSet,'Solver','FixedStepDiscrete');
set_param(configSet, 'SystemTargetFile', 'ert.tlc');

  2. To enable packing the generated code in an archive, set the option PackageGeneratedCodeAndArtifacts to true.

    set_param(configSet, 'PackageGeneratedCodeAndArtifacts', true)

  3. Generate code from the model.

    slbuild(model);

  4. To specify the model configuration for the Polyspace analysis, use a pslinkoptions object. Create this object by using the function pslinkoptions. To run a Bug Finder analysis, set psOpt.VerificationMode to 'BugFinder'.

    % Create a Polyspace options object from the model. 
psOpts = pslinkoptions(model);

% Set properties that define the Polyspace analysis.
psOpts.VerificationMode = 'BugFinder';
psOpts.InputRangeMode = 'DesignMinMax';

  5. To specify Polyspace analysis options, create an options file. An options file is a text file that contains Polyspace options in a flat list, one line for each option. For instance, to enable all Bug Finder checkers and AUTOSAR C++14 coding rules, create a text file named OptionFile.txt. In the text file, enter:

    -checkers all
-autosarcpp14 all
    Save the options file. You can save the preceding options in an options file named Options.txt in the default work folder.

    See Complete List of Polyspace Bug Finder Analysis Engine Options.

  6. Start a Polyspace analysis.

    • To specify the model configurations for the Polyspace analysis run, set the object psOpt as the optional second argument in pslinkrunCrossRelease.

    • Because the code is generated as standalone code, set the third argument asModelRef to false.

    • To specify the Polyspace analysis options, specify the relative path to the created options file as the fourth argument.

    %  Locate options file
optionsPath = fullfile(userpath,'Options.txt');
% Run Polyspace analysis
[~,resultsFolder] = pslinkrunCrossRelease(model,psOpts,false,optionsPath);
bdclose(model);
    The character vector resultsFolder contains the full path to the results folder.
