@User @User Hello, I wanted to look at the information like minimum skew, maximum skew, insertion delay etc. at the CTS stage. I don't see this info in the log file and there are no files being generated under the
reports/cts
directory. Please guide me towards it. Thank you.

@Wajeh ul hasan: At the moment, nothing is generated directly after CTS, although is is not a good practice, you'll find some statistics in logs/cts.log, but I'm sure you're looking for a more comprehensive report. I will work on adding those today. Thanks for noting this out.

Thank you, I look forward to it

@Wajeh ul hasan: Sorry forgot to tell you. Currently, we report timing after CTS, but the timing reports are in logs/*-cts.log.

Umm.. which timing report are you referring to? I have looked at the log file at
/logs/cts/cts.log
. I can see information like: 1. min slew 2. max slew 3. min cap 4. max cap 5. Number of sinks 6. Level of clock trees However I am looking for information about skew, insertion delay etc. For example, there is a variable
CTS_TARGET_SKEW
, if I set a certain value here, how would I know if it was met or not? @Amr Gouhar

@Wajeh ul hasan: The reports were added recently, so you'd need to use v0.3 onward to get those updates. Also, this value is not used by TritonCTS
CTS_TARGET_SKEW
, but used by simple CTS which is disabled by default as tritonCTS does a much better job in clock tree synthesis.
