In one of my project , i am using AXI VDMA to process the video frames. I have connected Read/Write Channel Clocks of the VDMA to 200 MHz.So the Read/Write operation is based on 200MHz only. Even though i am getting timing violation inside the AXI VDMA Path.
How to solve this issue?
I have attached timing report and design pdf.
In design pdf
FCLK_CLK2 37.125MHz (output resolution clock for HD@30fps)

What happen if you use a slower clock for the AXI4S interface of the VDMA?

Before I used two clocks in AXI VDMA . The 200MHz for Read Channel and 37.625MHz(Video Clock HD@30fps) for Write Chennel. But i had big timing violation. So i connected 200MHz to Read and Write Channel.

I sent you a email last week to upload your project but I didn't receive any files back. Did you get the email?
Do you have any progress?

If you change the memory map address width in the VDMA it should help meeting timing. Also make sure to use the max burst size.

What is your status on this? Were you able to make progress?
