Repair Antennas non-deterministic/faulty results #5325

Open osamahammad21 opened 3 days ago

osamahammad21 commented 3 days ago

Describe the bug

In https://github.com/The-OpenROAD-Project/OpenROAD/pull/5281 The CI is giving different result for sky130hd_ibex than my local machine run. The differences start at repair_antennas part, while the groute guides are identical. What's more weird is that at the end of repair_antennas, the number of antenna violations reported is 0 while after check antennas which is called right after it, the antenna violations are 1 (This is on the CI's result).

Expected Behavior

Same number of antenna violations reported by repair_antennas and check_antennas Same result on my machine and the CI's

To Reproduce

This is from a branch on my fork https://github.com/osamahammad21/OpenROAD/tree/drt-fix-update-design This is a non-determinism issue so I am not sure if this happens specifically on my local machine or does the difference appear on other machines as well. What's concerning more tho and I think would be the root of the problem is the difference in the antenna violations number we get from check_antennas and repair_antennas.

gudeh commented 2 days ago

The previous issue #5233 seems to be due to the same reason.

I noticed this when running the regression test in ./test/regression jpeg_sky130hd.

I ran with valgrind on a previous OR version and got the following log:

If you are seeing calls to tmg_conn from ant you are using an old version and need to update.

gudeh commented 2 days ago

Indeed. This valngrind log is from an older version. I actually got this log from my chat with you @maliberty. But it is interesting that values change in the same place as before, the number of diodes reported by GRT.

eder-matheus commented 1 day ago

@osamahammad21 I've fixed the mismatch of violations reported here: https://github.com/The-OpenROAD-Project/OpenROAD/pull/5346.

When running in gcp, I see the same results as you see. I get the same output in every run, so at least we have consistency in the same OS and machine.

Could you update the branch of your PR: https://github.com/The-OpenROAD-Project/OpenROAD/pull/5281? I can't access the results of the older CI runs, probably because we had some updates in the CI.

eder-matheus commented 1 day ago

Reopening it to keep investigating the non-determinist across platforms.
