Video Test Pattern Generator v7.0 - Upgrade from 2016.2 to 2016.3 version changes the behavior of Test Pattern Generator

Description

The additional features added to the Test Pattern Generator in the 2016.3 release allow users to select which test patterns to include in the IP. This was done in an effort to reduce logic utilization and improve performance, which makes it easier to meet timing.

This was not available in Vivado 2016.2 so an upgrade from the 2016.2 to 2016.3 version can change the default behavior of the test pattern generator. Symptoms of this problem include a missing test pattern(s) when running your project in software.

Below are the Vivado 2016.2 and earlier Test Pattern Generator options




Below are the 2016.3 Test Pattern Generator options.




 

Solution

To edit the Test Pattern Generator, open the Video Test Pattern Generator GUI and add the additional video test patterns by selecting the associated check box and regenerating.
