Re: [Gems-users] NEW QUERY!! Random Tester with Trace

[Niket <niketa@xxxxxxxxxxxxx>]

I am not sure whether Ruby does that currently. I guess you can add that by keeping track of what causes misses in CacheMemory.h

Cheers,
Niket

Thank you Niket,
Is there any way to classify these misses as capacity or conflict or cold start misses? I can see that the RUBY prints the status of the misses but does not indicate the type of miss. Is this supported in RUBY?

1. How do I specify the "Size" of a load instruction as in no of bytes of data to be fetched from memory in the tracefile of the Random tester?

g_DATA_BLOCK_BYTES in ruby/config/rubyconfig.defaults

2. I would like to know more about the CacheMsg class. where can I find this .h file?

Look in ruby/generate/<your protocol>

Niket

Thanks for helping me.

You can use the -z option to input a trace file directly to tester. You can find more information at http://www.cs.wisc.edu/gems/doc/gems-wiki/moin.cgi/How_do_I_understand_a_Protocol

Hi,
I have a trace file that has the following fields:- address, access type, thread id. I need to map this fields to the Tester module to feed this as inputs to RUBY. I am not interested in a timing driven simulation.
When I looked into the tester code, I find that function "InitiatePrefetch" in Tester/check.c generates Random address inputs. Is this correct? Do i need to modify this function to provide the inputs from my trace file? or is there any other way to input my trace file to the RUBY simulator?

thanks,
Ashwath
