LogiCORE IP Video Timing Controller - Why do I not see blanking signals generated, when I select the blanking signal detection?

Description

Why do I not see blanking signals generated, when I select the blanking signal detection?

Solution

When selecting the Detection option for the Video Timing Controller, the user should only select the signals which the user will be providing. If the user selects HBLANK and VBLANK but does not provide these inputs to the Timing Controller Generation circuit, the controller will not be able to generate the HBLANK and VBLANK output because no inputs will be measured.

Please see (Xilinx Answer 32754) for a detailed list of LogiCORE Video Timing Controller Release Notes and Known Issues.
