Huge runtime for AES sky130hd

[gadfort]

Describe the bug

In the CI runner, the AES sky130hd takes 3+ hours to complete, while other platforms are < 30 mins (except for ihp130, which is 1hour+). This appears to be related to the large number of shorts reported after iteration 0: 22k+ (which take 50 iterations to resolve, a little over 2 hours), the same can be said for ihp130.

Expected Behavior

Routing runtimes based on the selected density settings that are comparable with other platforms with a lower number of initial shorts.

Environment

Jenkins CI env.

To Reproduce

Observed via jenkins interface, should be reproducible.
