After a system has been generated, there are two ways to debug applications that are running on it:
Create a batch file and run the debugger from a debug server, using the Model Shell application. This method is useful for running long or repetitive tests on the same system. See Batch mode debugging.
Start the Model Debugger GUI directly from System Canvas. This is the most convenient way to debug the system. See Debugging from System Canvas.
You can debug the LISA+ code that defines the model itself. See Using other debuggers to debug LISA source.
