Megaboom: 20k routing congestion DRCs with just 0.24 placement density #6066
Comments
@jeffng-or did increasing the number of overflow iterations help? |
It's currently running as part of my sweep. Will report back once it's completed |
No, I checked, the artifact is available for the git commit below. Here is after 30 iterations(default GLOBAL_ROUTE_ARGS). Note that I think the number of markers is capped at 10000, but one could hope that the 10000 markers are representative for where the congestion is?

@oharboe , thanks for the confirmation. I tried running the 30 iterations in a sweep, but the multiple jobs killed my machine. |
Describe the bug
The current BoomTile design fails global routing with 20k routing congestion DRCs, but the placement density is only 0.24. There appears to be a lot of space especially at the top of the design.
The tarball with the design data can be found at: https://drive.google.com/file/d/15grexnVmOSpRFUK8gHTMJj7DnZpPgzpL/view?usp=sharing
Expected Behavior
Either better placement or the ability to global route the design.
Environment
To Reproduce
After unpacking the tarball, you can bring up the GRT view in the GUI with:
The gui keyword will bring up the GUI.
