Errors similar to the following occur when I run behavioral simulation using the Video Scaler v8.0:

This is a known issue that can occur in some configurations of the Video Scaler and will be fixed in a future release of the tools.
This is a simulation only issue, and does not affect implemenation. Users can still successfully implement a working bitstream that can be run in hardware.
There are two ways to work around this issue:
