`test_ip_eth_tx_64.py` hangs
EdwinEstep opened this issue · comments
After the latest commit to ip_eth_tx_64.v (9b5a8cf24aeeeee9d0eadabb3136f7e7722544e2), the MyHDL testbench hangs indefinitely:
The only changes I made were to tell the testbench where to find the myhdl VPI bindings. Here's a sample of the log output:
Note that this doesn't happen before that commit. Also note that the 8-bit version does not hang, completing in about 16seconds on my machine:

Hi,
Could you let me know, how to run the simulation for this design. I have installed "cocotb", "cocotbext-axi, cocotbext-eth, and Icarus Verilog (version 10.3), however when I run make WAVES=1 in this path "verilog-ethernet/example/Alveo/fpga_25g/tb/fpga_core" I get following error

It looks like you need to install scapy, which is used for constructing and deconstructing network packets for testing.

Thank you very much, I am able to run the simulation tests after installing scapy
Glad to hear it!
