That's ticks. You would have to divide by the cycle time to get cycles. curCycle() should be curTick()/cyclePeriod() (cyclePeriod is the ticks per cycle. E.g., 500 for 2 GHz). See https://gem5.googlesource.com/public/gem5/+/refs/heads/master/src/sim/clocked_object.hh#65.

However, I have one more question. Do the debug prints here print out the ticks or cycles on the left (underlined)? If ticks, then how can I get the cycle value? I see there were similar questions asked earlier but I didn't understand the explanations provided. What does the call curCycle() return? I used it but the value returned matches the value on the left side of the print statements below. 500: system.ruby.l1_cntrl0: MESI_Two_Level-L1cache.sm:537: Issue GETS address: 0x70000 78000: system.ruby.l1_cntrl0: MESI_Two_Level-L1cache.sm:845: Load complete address: 0x70000 Regards, Abhishek Bhattcharyya ________________________________ From: gem5-users <gem5-users-boun...@gem5.org<mailto:gem5-users-boun...@gem5.org>> on behalf of Jason Lowe-Power <ja...@lowepower.com<mailto:ja...@lowepower.com>> Sent: Monday, April 15, 2019 11:12 AM To: gem5 users mailing list Subject: Re: [gem5-users] Debug prints in FS mode using script Hi Abhishek, Check --debug-help. You probably want --debug-file=<filename> and you may want --debug-start=<tick> when debugging Ruby protocols in FS mode. I've also found it useful to use a named pipe for the debug file and pipe it though `tail` to get only the last n lines (where n is usually megabytes to gigabytes). PS: Using the Ruby random tester is a way to debug protocol issues without having to wait for hours (days if you have tracing on) for Linux to boot.

I have added new debug prints to the gem5 code to trace RubySlicc request and response actions. How do I redirect the debug prints to a new file and collect the trace in this case?
