Have a look at SIMICS_remove_timing_model in interface.C. Be aware it might be a slightly deprecated, but it does the trick for Simics 2.2.x.

I have another related question:

Is there a way to switch the sending of memory accesses to ruby on and off?

thx for the info. I just looked in the code and saw that there is no code inside printdata().

If I just want to save the cache state for warmup purpose on future runs, should I just use ruby0.save-caches? and ruby0.load-caches to warmup?

What exactly is saved when I do save-caches? just the addresses of data stored inside the cache with the corresponding tag bits? or is the actual data stored?

thx Mike.

See CacheMemory.h.  You could just change printData() to call print()
which is implemented.

I forgot why this got implemented the way it did.  I think printData() was
meant to dump out the raw data values, and that print() was meant to dump
the Entry information (states, etc)

I tried dumping cache state when running with both opal and ruby (using
the MOESI_CMP_directory protocol, and I get the following message in the
.cache file:

printData() not supported

Does the cache state printing only work for certain protocols?
