| # PRE-ASSIGNPIN PLUG-IN |
| ################################################################################## |
| # |
| # This example plug-in script should be called before invoking assignPtnPin. |
| # |
| # - Assign partition pins |
| # - Set pin-placement parameters for pin-assignment: |
| # - pinDepth, to avoid min-area violations when |
| # DRC is run at the partition-level |
| # - pinPitch and pin-layers set to single layer |
| # for each side (T/B/L/R) |
