I might be speaking out of turn here since I don't really know what the replay block does. But in the past, I successfully created a block that used a .coe file as a generated signal I transmitted over and over again. It was a pretty easy OOT module that just used a Xilinx core if I remember right. --------- Original Message --------- Subject: Re: [USRP-users] RFNoC Replay block for E310?

Hi Rob, The Replay block was only tested with X310/N310. E310 doesn't have the PL DRAM connected like it is on those products. In theory the Replay block could be used on E310, but it hasn't been tried. It would take some work to get the memory interface set up and connected to the Replay block (you would want to hook it up similarly to how its done on X310/N310), and there might be resource challenges depending on what you're trying to fit in the design. But I'm not aware of a specific reason why it couldn't work.

Now, I would like to do the same with an E310. After some quick investigation, I noticed that the "use_replay" logic has been included in both "n3xx_core.v" and "x300_core.v" but not in "e310_core.v" or any other E310 verilog files. I also noticed that application note AN-642, Using the RFNoC Replay Block, specifically mentions support for the X300/X310 and N310, but no mention of the E310. I'm wondering if I just need to modify "e310_core.v" to implement similar logic to that in "n3xx_core.v" and/or "x300_core.v" in order to get this working on the E310? Or, is there some reason that this will not work such that I am wasting my time? Thanks.
