Sky130-OpenRoad Tutorial Place and Route Fail

[johnw08]

Hello,
I'm following the Sky130-OopenRoad tutorial and I was able to get it work until the Place and Route part. After running "make par tutorial=sky130-openroad" command I got the following error message:

[par] [Exec ...d/bin/openroad -no_init -log /...] create_clock clock_uncore_clock -name clock_uncore_clock -period 50.0
[par] [Exec ...d/bin/openroad -no_init -log /...] [ERROR STA-0489] pin 'clock_uncore_clock' not found.
[par] [Exec ...d/bin/openroad -no_init -log /...] Error: clock_constraints_fragment.sdc, 1 STA-0489
[par] ERROR: OpenROAD returned with a nonzero exit code: 1.

Please help. Thank you!

I found out the problem. The clock name should be "clock_uncore" instead of "clock_uncore_clock" in all the yml config files. Now I ran into a different error.

Hey John,
I am getting the same detailed placement error when I try the Sky130+OpenROAD tutorial. Did you find any fix for it?
Thanks,
Alex
