Difficulties getting RV64I working in lockstep

Trying to get RV64I working in lockstep.
Copied config/rv64gc/imperas.ic into config/rv64i

wsim rv64i tests/riscof/work/riscv-arch-test/rv64i_m/I/src/addi-01.S/ref/ref.elf --lockstepverbose

Immediate PC mismatch

# Error (IDV) PC mismatch (HartId:0, PC:0x0000000080000000 rvtest_init+0):
# Error (IDV) Mismatch 0>
# Error (IDV)   . dut:0x0000000000000000 
# Error (IDV)   . ref:0x0000000080000000 rvtest_init+0

@rosethompson looks like an initialization issue. Do you have any suggestions?

Seems to be that as soon as Zicsr is disabled Imperas is no longer able to get the PC.

The signals in wallyTracer.sv might give some clues, but I don't immediately see a signal gated by Zicsr.
