10.1.02 System Generator for DSP - During simulation of my FFT v5.0 design, why do I receive the error: "FFT simulation did not complete sucessfully" when my FFT is configured for dynamic transform size?

Description

When my FFT is configured with a dynamic transform size and scaled at the butterfly stages, I receive the following error after simulation has run for a little while:

"FFT simulation did not complete sucessfully.

Error occurred during "Simulation Update State"."

Solution

This is a known issue with the FFT configuration which is caused by a communication problem in the FFT simulation model.

To work around this issue, generate the FFT core in CORE Generator and bring it into System Generator as an HDL Black Box.

This problem will be addressed in a future release.
