11/21/2022, 12:45 PMhi I run all the scripts defined in static timing analysis and got no error, after running final make caravel-sta I got these at the console:
Found 78682 unannotated nets.
Found 724 partially unannotated nets.
you may want to edit sdc: /home/mbaykenar/Desktop/workspace/mpw7_yonga_soc/caravel/signoff/caravel/caravel.sdc to change i/o constraints
check /home/mbaykenar/Desktop/workspace/mpw7_yonga_soc/signoff/caravel/openlane-signoff/timing/max/s
logged to /home/mbaykenar/Desktop/workspace/mpw7_yonga_soc/logs/top/caravel-timing-s-max.log
make[1]: Leaving directory '/home/mbaykenar/Desktop/workspace/mpw7_yonga_soc/deps/timing-scripts'
You can find results for all corners in /home/mbaykenar/Desktop/workspace/mpw7_yonga_soc/signoff/caravel/openlane-signoff/timing/
so did I pass or fail :l

11/21/2022, 1:45 PMYou should also check *unannotated.log file to see any valid FF is not getting clock or not

11/21/2022, 1:55 PM@Dinesh A thanks a lot, I will
Burak Aykenar
11/21/2022, 1:58 PMin the meantime, I also push efabless new repo and rerun pre-check and see if any error comes out
Burak Aykenar
11/21/2022, 2:08 PMI did run
*grep -r -c "VIOLAT*"*
in signoff/caravel/openlane-signoff/timing
the results are not so heartwarming 😅

11/21/2022, 2:12 PMan example violation message is:
min/s-min.rpt: -4.5165 slack (VIOLATED)

Dinesh A
11/21/2022, 2:13 PMYes, first priority is to check *min.rpt to check any hold violation in your design
Dinesh A
11/21/2022, 2:18 PMIf your block level partition are clean during openlane flow, then you should get only inter-block violation only. You need to cross-check if caravel.sdc need any update specific to your design. In the flow it gives warning saying SDC may need a update.
Found 78682 unannotated nets.
Found 724 partially unannotated nets.
you may want to edit sdc: /home/mbaykenar/Desktop/workspace/mpw7_yonga_soc/caravel/signoff/caravel/caravel.sdc to change i/o constraints

11/21/2022, 2:20 PMyes thanks a lot, during macro hardening I don't get these violations but at the integration level I don't remember adding any extra constraint or editing anything
d
Dinesh A
11/21/2022, 2:22 PMYou need to cross-check the path to understand the issue, I see some of the MAX corner violation are related to Caravel SOC which can ignored.
