LogiCORE xFFT v3.1 Patch - Why do I see memory collisions, or an incorrect output, when using the Streaming I/O mode?

Description


General Description: 
Why do I see memory collisions, or an incorrect output, when using the Streaming I/O mode?

Solution


These memory collisions are valid, and should be checked in Timing simulation, to make sure that the output is not corrupted. 
 
This will be fixed in the xFFT v3.2, which should be available with 7.1i IP Update #1. 
 
7.1i IP Update #1 will be available in early Summer.
