Routing with Soft-Penalizing Pixels on a Found Path

Routing a circuit path includes selecting pixels on the circuit path based at least on penalty values associated with the pixels. Pixels on a rejected circuit path are penalized by increasing their penalty values. Re-routing a rejected circuit path allows for pixels on previously rejected paths to b...

Zusammenfassung:Routing a circuit path includes selecting pixels on the circuit path based at least on penalty values associated with the pixels. Pixels on a rejected circuit path are penalized by increasing their penalty values. Re-routing a rejected circuit path allows for pixels on previously rejected paths to be considered when rerouting the rejected circuit path, rather than being eliminated outright.
