cvw/sim/verilator/Makefile
Rose Thompson 9471dcd296 Refactored the fpga and testbench so the RVVI can be synthesized cleanly and simulated without any major code changes.
Adds three new configuration parameters to control enabling the RVVI packetizer and how much latency should exist between packets and the initial startup delay.
