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

[Niket <niketa@xxxxxxxxxxxxx>]

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>

Cheers,
Niket

Thanks for helping me.

regards,
Ashwath

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
