[Gems-users] TM Simulation (SIMICS SEG FAULT)

[BYONG WU CHONG <bernard.chong@xxxxxxxx>]

Hi, I was running LL TM from GEMS 2.1 and I got this SIMIC SEG FAULT error.

...

This is the whole dump of the CLI window with XACT_DEBUG_LEVEL = 9

This is simulation's output, which I don't think it helps much.

This is the LL TM python script I copied and modified from ATMTP's (but I disabled all ATMTP definitions).

This is the actual Simics script I used.

I got the bindings right, and I think I got the initializations right according to this thread,
https://lists.cs.wisc.edu/archive/gems-users/2008-March/msg00030.shtml
but it seems something is wrong.


Please help me to bug this error.
