pinDensityAwarePlacement

layoutXL.placement pinDensityAwarePlacement boolean { t | nil }

Description

Considers the pin densities of standard cells while optimizing placement and improving routability. The assisted placement options are also pin density-aware. The pin density consideration can result in larger spacing between the placed standard cells.

Pin density awareness is a heuristic to improve routability, and therefore is not checked during placement verification.

The default is nil.
