Hi Aditya,
I suspect you are connecting a CommMonitor between the tol2bus and membus in
parallel with the L2 cache. You need to use it as a kind of extension cord. The
monitor exposes all addresses from its slave port to the master port, so you
have effectively bypassed the L2. Instead, connect it in series with the L2
(before or after depending on what you want to do).
Good luck.
Andreas

Andreas,
I am using se.py file for configuration.
I have added following lines in /configs/common/CacheConfig.py
system.monitor2 = CommMonitor(trace_file="cachetrace.txt")
system.monitor2.master = system.tol2bus.slave
system.monitor2.slave = system.membus.master
When I run any code with these lines, it results in "error:
The log for execution is attached:

Let me know what else I can try.
