Reading simulation time to a variable

Hi Stephen,
But how do I tell xrun where to stop and measure the time?

Please note that I am entering my commands in the console.

Cheers,

Pedro

Hi Stephen

I cannot make this work.

So, do I have to call xrun as "xrun -status -status3" or as "xrun -status -status 3" ?
Am I missing something?

Best regards,

Pedro

Hi Pedro.

It's the first one: "xrun -status -status3".

The "-status" tells it to dump a CPU/memory summary at exit, and "-status3" tells it to dump the more verbose version of the summary, with a break-down for the individual tool components.

Hi,

Thanks for the answer.

But how does the simulator know when to dump the summary ? I should have to write some command to tell the simulator that I want to generate the report at that point of the code.

Otherwise, how xrun would know that the program had ended?

Hi Stephen,

Can you please give me your inputs on my last question? I would really appreciate it.

Best regards,

Pedro

The summary is dumped when you exit the simulator.

This is the output I have 

Aggregate audit (2:30:10 PM, Fri Dec 10, 2021):
Time used: CPU = 47.9 ks (13h 18m 36s), elapsed = 13 ks (3h 36m 17s), util. = 369%.
Time spent in licensing: elapsed = 20.6 s.
Peak memory used = 2.33 Gbytes.
Simulation started at: 10:53:53 AM, Fri Dec 10, 2021, ended at: 2:30:10 PM, Fri Dec 10, 2021, with elapsed time (wall clock): 13 ks (3h 36m 17s).
spectre completes with 0 errors, 89 warnings, and 22 notices.
xmsim: Memory Usage - Final: 1289.0M, Peak: 1345.3M, Peak virtual: 1734.9M
xmsim: CPU Usage - 3314.5s system + 46984.3s user = 50298.8s total (14821.7s, 100.0% cpu) (myhost)
xrun: Time - 15071.8s
TOOL: xrun(64) 20.05-t004-20201018: Exiting on Dec 10, 2021 at 14:43:02 CET (total: 04:11:12)

Do I have to divide the time, returned by the simulator, by the number of cpus I've used? Otherwise, the result doesn't make sense.

15071 seconds is 4.18h, which is more than the "wall clock" value.
