Video Scaler v3.0 - Why does intr_output_error assert unexpectedly at the beginning of my simulation?

Description

Why does "intr_output_error" assert unexpectedly at the beginning of my simulation? 

Note: This issue affects the Video Scaler v1.0, v2.0, v2.1, v3.0, and v4.0.

Solution

The "intr_output_error" is a flag that is asserted when the "frame_rst" signal is asserted but the previous frame did not complete processing. 

The reason this asserts at the beginning of a simulation is that there have been no previous frames to complete.

You can safely ignore "the intr_output_error" at startup.

This issue is scheduled to be addressed in the next release of the Video Scaler.
