Nexys Video DPTI Demo

Question

I was trying to use the DPTI Demo provided with the Adept SDK 2.4.2 with a Nexys Video Board. I am on a RHEL7 host machine. I can currently get the Synchronous DPTI (Port 1) to work upto ~200k bytes after which the demo times out. Similarly I am unable to get the demo to work in Asynchronous mode (Port 0) at all. Is this expected behaviour or am I missing something?

Hi @chiraagj,

After doing some research I believe that the issue is in the HDL and that you need to use the finite state machine optimization option in Vivado. What version of Vivado are you using?

cheers,

Hi @chiraagj,

It is a setting in vivado that stops the tools from optimizing the finite state machine and removing certain registers. My understanding is that this should fix both issues. I have reached out to try to find where that feature is in Vivado 2016.3. I will post here when I find out.

cheers,

Jon
