Why do of some video test patterns not generate outputs in the example design?
When trying the HDMI Subsystem Example Design on the KCU105 board, the following Video Pattern did not work:
In the Vivado 2016.3 Test Pattern Generator v7.0 (Rev. 4) not all the tests patterns are enabled by default. See (Xilinx Answer 68009) for more information.
This has been addressed in the HDMI Example Design for the HDMI Transmitter and Receiver Subsystems v2.0 (Rev. 4) in Vivado 2017.1 and later.
The menus will dynamically update to enable features based on what options are selected in the Test Pattern Generator.
You can work around this by editing the Test Pattern Generator used in the HDMI Subsystem example design.
Open the Video Test Pattern Generator GUI and add the additional video test patterns by selecting the associated check box and regenerating.
