Working with Arm Fixed Virtual Platforms (FVPs) is a great way of cutting months from your project. Models give you a programmer's view of a complete Arm system, allowing you to test and debug software long before you have access to the Silicon. With the Models Platform Configuration Editor, it's easy to import, connect to and debug a model in DS-5.
To open the DS-5 Configuration Perspective, select Window > Perspective >Open Perspective > Other... then select DS-5 Configuration.
Select File > New > Configuration Database and enter a name for your database.
This creates a folder you can see in the Project Explorer view.
Right-click in the Project Explorer view and select New > Model Configuration. Choose the database to create the entry, and click Next.
Select Launch and connect to specific model, and then click Next. To browse to the folder where your model is located, click File . Select the model executable, for example FVP_VE_Cortex-A15x4-A7x4.exe, and then click Finish.
Note: You may find that any file dependencies that the model executable might have, such as .dll files need to be in the same folder as the model executable. You should consider this if you decide to copy your executable into the DS-5 /bin directory.
DS-5 launches the model for you and detect its configuration. This is presented as a view in DS-5 with the title model.mdf.
To import your configuration, click Import.
This creates a new entry in the DS-5 configuration database, which allows DS-5 to debug the model.
To debug your model configuration, click Debug.
The Debug Configurations dialog loads and contains your imported model ready to debug.
Customize your configuration
Model Devices and Cluster Configuration Tab
This is the default tab, which allows you to customize the core and cluster configuration, along with associations for peripherals such as flash, mouse and keyboard.
For each CPU, you can view and edit L1 instruction and data cache associations, as well as translation lookaside buffers. Likewise, you can do the same with the L2 cache for each cluster.
Debug Connections Tab
In this tab, you'll see a list of all the available debug connections. To create a new connection, right-click on the top level folder and then define whether it's big.LITTLE, SMP or AMP by right-clicking the new connection. To populate the connection, drag and drop cores or clusters from the list in the right hand panel.
Model Launch Configuration
This tab allows you to pass the model launch parameters, which you would normally either add to a batch file or define in the Debug Configurations dialog.
The final tab in the configuration enables you to generate a CADI or RDDI log when the model runs.
