You  You can generate code, for example, from the SysML UML Class structure,  UML State Machine, or SysML Internal Block Definition diagrams Blocks. The code generation and building are executed via the the 3DEXPERIENCE platform.  Key concepts and capabilities CATIA Software Producer offers the following generation capabilities: Generating C++ classes from UML structured classes Generating C and C++ code from UML behaviors Generating target dependent middleware code including AUTOSAR classic and adaptive Generating and compiling code for FMU Generating code from a model persisted as a file, or in TeamWorkCloud or in the 3DEXPERIENCE Platform. Generate code containing traceability information establishing the relation from the model items to the code. Info For more information about the Software Production Engineering application, see Software Production Engineering. CATIA Software Producer uses the concept of target configuration to guide the user in configuring the code generation process. Prerequisites The CATIA Software Producer Client plugin is installed in your modeling tool. Learn more about how to download the installation files. The 3DEXPERIENCE platform is on the cloud. You have the Software Production Engineer Role. It will give you permission to use the service. Working with the code generator Before starting to work on code generation, first, you have to connect to 3DEXPERIENCE by entering the URL of the Software Producer cloud server. After that, you will be able to log in with your regular identifiers. Info For information about how to authenticate with the 3DEXPERIENCE platform, see Authentication with 3DEXPERIENCE platform. If you start working with CATIA Software Producer for the first time in your project, a dialog will open to configure the local workspace path which will host generated resources. Image Added Configuring the code generator The principle  The generated code is composed of a behavior part and a middleware part. It is identified as a target. The behavior part is relative to the behavior of your application (such as State Machine) whereas the middleware part is target-specific and is generated from the architecture of your application (such as IBD). Image Added As the code is composed of multiple entities, multiple configurations are required. You will be guided in the configuration through multiple dialogs to create the target configuration. Anchor code_generation code_generation To generate configure the code in the SysML diagramgenerator Do one of the following: In the open SysML diagram , select : Select the element you want to generate. Note Note Use the Commit section to commit the code to the branch associated with the input element. configure the target of your generation: Select the operation in charge of the target you expect. For example, the target can be C code, C++ code or an FMU. Image Added (optional) Check and specify (optional) Specify the download location if you want the results saved on your local file system. The generated files will be downloaded under this location, in a folder named after the configuration name. Click the OK button. If the operation you selected (for example FMU Target Build) requires additional operations to be executed, additional dialogs open to configure them. Once the end of the configuration process is reached, i.e. you have fully configured your target,  To save the specified properties, click the Apply button. under the Configuration package you will find: The Generator Configurations package1: this is where classes are created to save common properties of generators (parameters especially). The Target Configurations package1: this is where packages are created to save the flow of a target. Within this package,  classes are created to save specific properties for each SPO (download options, input, and generator mapping).  1You can change the default name of those packages in the Environment Options > CATIA Software Producer Client General Properties > Configuration section Info The configurations
Info

• some properties are attached to the input element (commit and download options);
• other properties are attached to the configuration Class element (SPO–related options). The Class elements are created to save the SPO configurations in the model.

Executing the code generator

To execute the code generator

1. Do one of the following:
   
   • In the open SysML diagram:
     1. Select the element you want to generate. If you do not select any particular element in the diagram, the entire diagram view is selected as the generation input.
     2. In the diagram toolbar, click the Image AddedGenerate Target button and choose Generate Target.
        Image Added
   • In the Containment tree:
     
     1. Select the element you want to generate. 
     2. From the selected element's shortcut menu, select Software Code Generation and click Generate Target.

The target will be generated based on your configuration:

• If you click Generate Target, the generation will be performed for the modified elements in the model.
• If you click Full Generate Target, the generation will be fully performed.

Edit or change your configuration

To edit generator

All the configuration properties are stored in a Class element, which is created when you click the Apply button in the Generation Details dialog. You can edit the configuration properties when needed.

To edit configuration properties

1. In the Containment tree, right-click a Class element of the needed generator configuration.
2. In the shortcut menu, click Software Code Generation and select Edit Configuration.
3. In the open Generation Configuration dialog, make your changes.
4. Click OK Apply and then Close.

You can deactivate the SPO you do not need.

To deactivate the SPO

1. In the main menu, click Options > Environment. The Environment Options dialog opens.
2. In the dialog, go to CATIA Software Producer Client > Operations.
3. Select the needed operation and click the Change activation status button.

You can switch projects (or even shut down your computer, saving your work first) while waiting for the generation result as it is running on the cloud and as the widget keeps the ids of the cloud assets in the record files located in <local workspace path>\etc\operations\spoRecordFile.json (you have access to it if you need it for the debugging purpose for example). When you come back, another dialog will tell you that operations were running while you were away and will propose you inspect the result and download it.

If you have configured multiple targets for the same input, you might want to change the default one (which was created last).

To change the default target configuration

1. Do one of the following:
   • In the diagram toolbar, click the Image AddedChange Default Target button.  
   • In the selected element's shortcut menu, click Software Code Generation > Change Default Target. 
2. Select the target you want to use.

3. Click OK.

Local workspace of the software producer

Under the local workspace, you can find the generated files, if you have selected the download option and left the default location (as seen above) in the configurations. You can also find some other files under an “etc” folder:

• <Local_workspace_path>
  • <componentA_name>
    • <configuration1_name>
    • <configuration2_name>
  • <componentB_name>
    • <configuration3_name>
    • <configuration4_name>
  • etc
    • operations
      • json³
    • backup²
    • logs
      • log⁴

¹You can change the root of the local workspace path in the project options.

²By default, a backup of your downloaded files is saved in this folder so that in case something wrong happens with the download of new files, you can still reach your previous files. You can disable this option in the Project Options 

³SPO Report files are rotated by size and date so that you might see multiple report files here.

⁴Log files are rotated by size and date so that you might see multiple log files here.

RoundTrip

The roundtrip action is a feature available for State Machines and Opaque Behaviors. Using the roundtrip action, you can add the modification you made in the code in between BEG_USER_CODE / END_USER_CODE tags (in files commonly named <ComponentName>_usr.c), back into the model and synchronize the file on the workspace on the cloud.

Software Producer Logs

In the Software Producer Log panel, you can see the messages of the running SPO.

This information is saved in the log file next to your project files. To open the log file location quickly, in the Software Producer Logs window, click the Show Log File button. Each project has its own log file.

A log file for general Software Producer messages not related to a specific project is stored next to the modeling tool log file.

At the bottom right corner of the modeling tool, in the progress bar, you can see whether the SPO generation is running. After the SPO generation is completed, the notification is displayed showing the status of the generation.in case of failure or always if the verbose mode is activated (Environment Options > CATIA Software Producer Client General Properties > Notifications section).

Validation Results

When an SPO operation produces a report, the plugin reads it and opens it in a Validation Result window if any element has a diagnostic associated.

A diagnostic is associated with a rule consisting of a severity, message, and source.

You can navigate to the source in the Containment tree.  If you need to show more details concerning the rule or open the full report, right-click the appropriate lines of the table.

You can turn off the Validation Results window's opening after the SPO operation produces a report.

To turn the validation report off

1. In the modeling tool main menu, click Options and select Project.
2. Set the Show Validation Report property to false.

The full set of code you need to generate to cover your target is composed of at least a component and a target-specific part. Component part is relative to the behavior of your application (such as State Machine) whereas the target-specific part is relative to the architecture of your application (such as IBD). In other words, target specific is the binder and the link between the component and the target. As one does not go without the other, this is why at the end of the IBD generation, a dialog will ask you if you want the applicative code to be automatically generated if you have not yet done it (or if it has changed).

Once the full set of code has been generated, you can launch a build SPO by clicking on the Build Image Removedbutton.

When you click a Build button, a dialog opens, wherein you need to specify the target and the available parameters (if there are any).

The code is downloaded to your file system following a specific folder hierarchy:

• esp_workspace¹
  • <componentA_name>[_<targetX_name>]
    • src
    • bin²
  • <componentB_name>[_<targetX_name>]
    • src
    • bin
• etc
  • backup³
  • logs
    • softwareProducer.log⁴

1. You can change the root of the local workspace path in the project options.
2. A bin folder is created only if the related component is the main component for the build.
3. By default, a backup of your downloaded files is saved in this folder so that in case something wrong happens with the download of new files, you can still reach your previous files. You can disable this option in the Project Options dialog.
4. Log files are rotated by size and date so that you might see multiple log files here.

The roundtrip action is a feature available for State Machines and Opaque Behaviors. Using the roundtrip action, you can add the modification you made in the code in between BEG_USER_CODE / END_USER_CODE tags (in files commonly named <ComponentName>_usr.c), back into the model and synchronize the file on the workspace on the cloud.
