There is no built-in way to have AnalyzeModelCode "implicitly" create or reference a code generation task in Process Advisor. The code generation task must be defined in the process model, either by you or by the default process template provided by Process Advisor, and referenced explicitly in your Polyspace analysis task's properties.
If you want to minimize scripting, rely on the default process model creation features of Process Advisor, which will manage task dependencies (including code generation) for you. For scripting and custom process flows, you must define all dependencies explicitly.
