This is a long shot, but I have been fighting with my rfnoc block the last few days trying to figure out why it won't work. I am basically combining the threshold block and the siggen block (so it takes in values, and spits out data based on the siggen parameters). My block has been spitting some samples on startup and then just stops. Digging around, what I can see is that the axi_fifo_short's FIFO primitive is filling up. If I add debug to my testbench, I can see that my data is slowly losing the war on reading as fast as I am writing. Once it is full, I end up in a deadlock it appears. Since this is somewhat custom, there probably isn't a good answer, but does anyone have a suggestion where to look into this? The main module where I think my axi_interfaces are getting screwed up somehow (on my end) is the axi_async_stream.v module. ANY help would be appreciated!!!!
