Hi Gouri Adsure,

I tested the design and found out that avmm_data_readvalid signal and avmm_data_waitrequest signal do updating as well check screenshot attached below.

One thing to take note that have you go to Tools -> In-System Sources and Probes Editor and toggle the Index S[0] to start?

Thanks,

Best Regards,

Sheng

Hello ,

So you are using same code which is mentioned above?

Because with same code we found that IP is not incrementing avmm_data_addr (13 bit address ) in the read operation.

Can you just check in code is there other logic for read operation

( Also why we increment addr by 8 bits any specific reason)

Thank you
