Well, apparently @ktbarrett's fix is not sufficient; `t_vpi_cbs_called` fails with that change. Unfortunately, I do not know enough about verilator internals or VPI callbacks to take a proper pass at...

I spent a bit more time poking around and have conditioned the fix on only the time-based callbacks, like so: switch (reason) { case cbAtStartOfSimTime: // FALLTHRU case cbNBASynch: //...

TBH, I have never directly interacted with the VPI, so I'm not sure what callbacks are available and exactly how they're supposed to behave. It seems like the spec doesn't...

Why in the *&(#$ would ANY API allow you to specify an absolute time for an event-driven simulator....if you want an absolute time for some reason, read the current sim...

Well, apparently `make test` does not actually run all of the tests.

UltraScale is not so great for 100G. The PCIe hard IP only supports gen 3 x8, which is only 64 Gbps, and Corundum doesn't currently support combining two PCIe interfaces....

Unfortunately I don't have any counters implemented inside the pipeline right now, it's on the to-do list. You did set the ports up, right? (ip link set dev up) And...

Depends on the length of cable you need. Under 2 or 3 m, use a DAC, it's cheaper. More than 3m, get AOCs, and whatever length you think you need,...

Yeah, there should be three LEDs on the board visible through the back of the card - one red, one green, one yellow. I cannot recall which is which off...

That seems reasonable. I have had issues attempting to loop a host back to itself when attempting to use ping or iperf due to how linux routes packets, but I...
