Hi,
(I apologize for multiple post, but had made a mistake in the subject of
the previous post. )
The configs/example/se.py script has a small error that does not allow
proper workload assignment to SMT threads. I made the following changes to
fix that part:
--- a/configs/example/se.py
+++ b/configs/example/se.py

I am simulating X86 with detailed core. The simulation aborts with the
following error:

Any ideas of what might be going wrong ? I'd be happy to provide more debug
information. Thanks for your help !
