[Gems-users] Simics 2.2 vs Simics 3.0 statistics difference

["Berkin Ozisikyilmaz" <boz283@xxxxxxxxxxxxxxxxxxxx>]

Hi,

Since my current licenses are expiring soon. I have been trying to run the
same scripts for the same experiments with the checkpoints created in simics
2.2 in simics 3.0. The total statistics seems to be significantly different.
I am just posting a part of the logs to show the difference. Has anyone
observed this? Is there a solution? Should I contact Simics forum and what
should I tell?

Thanks
Berkin
PS: If you need more details I can attach the whole logs too.
