Why do I not see component parameters in the System Generator canvas?

Applies to: Fast Models


This issue is seen for ARM models that are declared as extern. These extern components are ones that have been written by ARM in C++ and are provided as compiled binaries, no source is available for these components.

These components are made available in the canvas, via a LISA file, that declares the components and defines input and output ports. In System Generator 3.2, these LISA files did not reference the parameters that the compiled component and hence the parameters are not visible in the canvas.

This issue only affects the parameters visible in the canvas, the correct parameters are always present in the attached debugger when the system is simulated.

In Fast Models / System Generator 4.0 and later, the parameters are present in the LISA file and hence are visible from within the canvas
