Hi Everyone,

I have built a couple of RFNOC blocks (using rfnocmodtool), connected them
using the GRC, and ran the scheme on an X310.

My objective now is to measure the precise latency of each block. In other
words, I would like to run the complete flow and see any indication of the
signal passing through the RFNOC blocks and measure the time it took it to
pass each one.

I have noticed the GPIO interface but understood it is accessed via cpp
design only (And as stated above, I use grc).

Is there any other method to accomplish the above using the grc? Are there
any other accessible output port?

Thanks,
Steve
