Since we’re at the topic of using git for revision control, here’s my take on that: Git is a tool written for source code revision control, where history is useful....

$$$$ extraction tools use def + gds/oasis tiles for cap/res extraction, I've not encountered a flow where def FILL has been used, fill data is usually created by physical verification...

I'm running on a M1 with 16GB and logs using 4,6,8 cores look nearly identical. But comparing the 32-thread nightly log to my M1 logs, these are the differences I...

Why not ? Starting point is a legal placement that is known to route. And it’s not a congestion problem, just pin access to one of the macro pins. The...

loading the guide still leaves me with this one macro pin access violation, even with --latest OpenROAD v2.0-3684-ga120f938e read_lef ispd19_test6/ispd19_test6.input.lef.gz read_def ispd19_test6/ispd19_test6.input.def.gz detailed_route -guide ispd19_test6/ispd19_test6.guide -output_drc 5_route_drc.rpt -verbose 1 exit...

I kept this bug open because OR failed to fix 1 violation both with and without guides. It shouldn't just be closed because it's "old", but thanks for reminding me...

1) Using read_guides the runtime of 50min is much better then the 2h40min with groute. But drt is still 2.5x slower then in May 2022. 2) This is also a...

I was using global_route. Given that the std cells are completely blocked in M1 for either PINS or OBS, it shouldn't be using any M1 routing ... Both M1 and...

I didn't set a min routing layer. I was (wrongly ?) assuming that global route would take M1 pins/obs of std cells into account when computing routing resources, but when...

OpenROAD v2.0-8799-gfb20dbe66 (Jun 21 2023) finishes. Merge pull request https://github.com/The-OpenROAD-Project/OpenROAD/pull/3487 from The-OpenROAD-Project-staging/gui-race seems to have done the trick for OR on Apple Silicon too. So I this ticket can be...
