How long is this test supposed to run?
It takes 4:42 using sis on my computer which is a 2.9 Ghz i7 .
SIS is a slow simulator. On Qemu it runs much faster.
I agree, qemu runs crypt01 in about 8 seconds on my i7 host.
However, a problem with qemu-leon3 is that it does not skip
time during power-down. Running all sptests takes 2:10 on sis-leon3
while it takes > 30 minutes on qemu. An other problem is that several
spintrcriticalXX.exe do not terminate on qemu-leon3, so it is not
quite possible to replace sis with qemu at this point ...
Ok, I should have said, that SIS is an accurate simulator ;-)
The spintrcritical*.exe tests are a problem in general on Qemu due to
the translation block granularity of the execution. I helps to use the
-icount option, but the results are still not that good. My experience
is that for everything which is timing dependent Qemu is a bad choice.
Maybe we should use different simulators for different tests.
