padv.builtin.task.GenerateCode Class

Namespace: padv.builtin.task
Superclasses: padv.Task

Task for generating code with Embedded Coder

Description

This class requires CI/CD Automation for Simulink Check.

The padv.builtin.task.GenerateCode class provides a task that can generate code by using Embedded Coder^®.

You can add the task to your process model by using the method addTask. After you add the task to your process model, you can run the task from the Process Advisor app or by using the function runprocess.

To view the source code for this built-in task, in the MATLAB^® Command Window, enter:

open padv.builtin.task.GenerateCode

The padv.builtin.task.GenerateCode class is a handle class.

Creation

Description

task = padv.builtin.task.GenerateCode() creates a task for generating code with Embedded Coder.

task = padv.builtin.task.GenerateCode(Name=Value) sets certain properties using one or more name-value arguments. For example, task = padv.builtin.task.GenerateCode(Name = "MyCodeGenTask") creates a task with the specified name.

You can use this syntax to set property values for TreatAsRefModel, InputQueries, Name, Title, IterationQuery, InputDependencyQuery, DescriptionText, DescriptionCSH, Licenses, LaunchToolAction, and LaunchToolText.

The padv.builtin.task.GenerateCode class also has other properties, but you cannot set those properties during task creation.

Properties

The GenerateCode class inherits properties from padv.Task. The properties listed in Specialized Inherited Properties are padv.Task properties that the GenerateCode task overrides.

The task also has properties for specifying:

• General Embedded Coder Options for generating code using the function slbuild. For more information on the slbuild arguments, see slbuild.

• Advanced Caching and Parallel Code Generation Options.

General Embedded Coder Options

TreatAsRefModel — Setting that controls whether task generates reference model code or top model code

[] (default) | true or 1 | false or 0

Setting that controls whether the task generates reference model code or top model code, specified as either:

• [] — Allow the task to automatically identify whether a model is a top model or a reference model before generating code.

• 1 (true) — Only generate reference model code.

• 0 (false) — Only generate top model code.

By default, the task automatically identifies whether a model is a top model or a reference model before generating code. But you can specify TreatAsRefModel as true or false if you want to override that behavior and only generate reference model code or top model code.

Example: true

Data Types: logical

GenerateCodeOnly — Generate code versus an executable file

false or 0 (default) | true or 1

Generate code versus an executable file, specified as a numeric or logical 1 (true) or 0 (false).

By default, the task generates code only and does not build an executable file.

Example: true

Data Types: logical

false or 0 (default) | true or 1

Generate obfuscated C code, specified as a numeric or logical 1 (true) or 0 (false).

Example: true

Data Types: logical

GenerateTraceReport — Generate code traceability report

0 (false) (default) | 1 (true)

Generate code traceability report, specified as a numeric or logical 0 (false) or 1 (true). The traceability report can help you navigate more easily between the generated code and the source model.

To specify the name of the code traceability report, you can use the task property TraceReportName.

Example: 1

Data Types: logical

TraceReportName — Name of code traceability report

"$ITERATIONARTIFACT$_CodeTrace.xlsx" (default) | string

Name of code traceability report, specified as a string. The name must include the Excel^® spreadsheet file extension .xlsx.

To generate a code traceability report, specify the task property GenerateTraceReport as 1 (true). The built-in tasks use tokens, like $ITERATIONARTIFACT$, as placeholders for dynamic path resolution during run-time. For more information, see Dynamically Resolve Paths with Tokens.

Example: "$ITERATIONARTIFACT$_TraceReport.xlsx"

Data Types: string

Advanced Caching and Parallel Code Generation Options

Methods

Specialized Public Methods

This class overrides the following inherited methods.

run	Generate code using Embedded Coder Note You do not need to manually invoke this method. When you run a task using the Process Advisor app or the runprocess function, the build system automatically invokes the run method for the task. The run method inside this built-in task runs on a task object obj with task input input and returns a task result taskResult. The task result is a padv.TaskResult object that can store the results from pass, fail, and error assessments. If you inherit from this built-in task, make sure to use the same method signature inside your custom task: function taskResult = run(obj, input) ... end
dryRun	Dry run the task to validate task inputs and generate representative task outputs without actually running the task. The dryRun method inside this built-in task runs on a task object obj with task input input and returns a task result taskResult. The task result is a padv.TaskResult object that can store the results from pass, fail, and error assessments. If you inherit from this class, make sure to use the same method signature inside your custom task: function taskResult = dryRun(obj, input) ... end For more information, see Dry Run Tasks to Test Process Model.
launchToolAction	Launch the Embedded Coder app. Process Advisor uses this method when you open the tool associated with a task.

Examples

Add Code Generation Task to Process

Add a task that can generate code for each model in the project using Embedded Coder.

Open the process model for your project. If you do not have a process model, open the Process Advisor app to automatically create a process model.

In the process model file, add the GenerateCode task to your process model by using the addTask method.

codegenTask = pm.addTask(padv.builtin.task.GenerateCode);

You can reconfigure the task behavior by using the task properties. For example, to rebuild models if the build process detects changes in known dependencies of the model:

codegenTask.UpdateThisModelReferenceTarget = 'IfOutOfDate';
