Hi all, I'm trying to run a Vivado simulation to run 2mb of pre-recorded data through an RFNOC IP block. I've modified the testbench created by rfnocmodtool for this purpose. After sending about 5-10k data samples and recording the results, the Vivado flow seems to ignore future testbench commands (using display statements, breakpoints, and such, I've determined it will reach the end of the forked send/receive routines, and, after a while, rather than loop back for another round of send receive on more data, Vivado just stops executing the simulation commands in the testbench). I've tried restructuring how the simulation works (all 2mb of data as one giant payload, breaking the data into smaller chunks and iterating over send receive, etc.), and with each case Vivado just seems to eventually stop doing anything with the testbench commands. The simulation doesn't crash, and from the waveform all of the clk and other signals keep running, but no new data is ever sent. Any thoughts?
