CVI directly connected to CVO

Hi, 

 

In SOPC, the CVI --> Terminator and TPG --> CVO, the input format can be recognized correctly and output work correctly. 

Then the CVI --> CVO, and the CVO format is same as the CVI, but the CVO has no output. 

 

Does it possible to connect the CVI and CVO directly? 

 

Thanks, 

Regards.

yes, i've used TPG > CVO > CVI > CVO for debugging (around 9.1 if it makes a difference)

Hi, 

Thanks, now the CVI -> CVO works. 

But CVI always overflow and CVO always underflow, I guess something wrong in clock.
