HDMI Clock Lock failure

Hello

i'm doing HDMI TX simulation. But i have problem that the screen is blinking.

i think the reason is 'clock lock' signal.

When i simulate, the clock lock signal becomes zero intermittently and the screen blinks.

i check the clock frequency according to the 720p and it is right.

i don't know how to fix it.

thanks.

Hi @LeeYK,

Simulation is not supported for most Video designs.

This is because simulation is not practical due to the time it would take to get to lock in most situations.

Instead of simulation, we recommend testing directly in hardware. For this Xilinx provides many example designs that can usually be updated to work on your custom platform.

 

Depending on what you are trying to debug there is likely a better way to look at the problem.

Is there an issue you are trying to solve (besides no 'clock lock' in simulation) or are you simulating for a different purpose?

 

Thanks,

Sam
