Hi Jonathon, The test bench passes cases 1-4 but hangs on case 5. I even copied the noc_block_gain.v and noc_block_gain_tb.sv from the reference files attached on the tutorial website, and the test bench results are the same (hangs on case 5). Then I tried not loading the tutorial Gain module to the FPGA, but loaded the existing RFNoC Digital Gain block and used that in the GNU Radio Companion, but the "timeout on chan 0" error still is there.
Do you suspect case 5 failing for the tutorial Gain block is related to the stock Digital Gain block also not working?
