these really should not be happening.  however they are nonessential.

if this is just the bpermd test that's fine
> src/soc/fu/mul/test/test_pipe_caller.py

not fine.

> src/soc/fu/trap/test/test_pipe_caller.py
> src/soc/fu/compunits/test/test_trap_compunit.py 

these are expected.


> src/soc/fu/logical/test/test_pipe_caller.py

if bpermd that is an ISACaller random fault


> 3) Tests that hangs (enters infinite loops):
> src/soc/experiment/l0_cache.py 

not concerned

> src/soc/fu/compunits/test/test_logical_compunit.py 

probably again because of bpermd

if you re-run the logical tests multiple times they *should* succeed because
ISACaller receives random values that fo not trigger its bug.

the multiply one *is* of concern and needs high priority investigation.

can you check first that it works under pysim?
