I compared the exec.log with trace from other simulator. I think you are right and it should be swapped.

I tried * *simple system* * following https://github.com/lowRISC/ibex/blob/master/examples/sw/benchmarks/README.md and * *co-simulation system* * following https://ibex-core.readthedocs.io/en/latest/03_reference/cosim.html

It works, thank you!
