Description
Description
The new segment-based regression should give us a more precise approximation of per-layer capacitance.
PDKs:
- asap7
- gf12
- gf180
- ihp
- nangate45
- sky130hd
- sky130hs
Suggested Solution
Run regression with the data of all the designs we run in our CI and evaluate GRT DRT timing discrepancies.
Additional Context
This should wait for #4243 to be closed.
