Why does the Video Scaler test bench sometimes fail with a timeout error after the first frame?

解决方案

Depending on the configuration of the core, the clock speeds and the input resolution, the time between frames may vary.  

The default timeout in the test bench is not long enough in some cases.

You can work around this by modifying the timeout value in the Test Bench on line 200 of the axi4s_video_mst.v file to be the size of the largest supported frame in order to avoid the time out situation.


From:
 

timeout        = 10000;

To:
 

timeout        = (4096*4096);
