Hi Yu, What changes did you make to the ethernet dev file? If you only get 2k packets, maybe it's only during the 200e6 period that it's actually running (the 1e9 period is much longer). If you can figure out when packets stop transmitting, you can try using the various Ethernet trace flags (see base/traceflags.py) to try to track what's going wrong with the Ethernet device by outputting a trace around that time. To start tracing at a specific cycle, add "--Trace.start=<cycle num>" to the command line, and use "--Root.max_tick=<max cycle num>" to limit your simulation length. I hope this helps, Kevin Zhang, Yu wrote:
