Abstract

See full text

Some embodiments of the invention are placers that use diagonal lines in calculating the costs of potential placement configurations. For instance, some embodiments estimate the delay cost of a placement configuration by accounting for the potential use of diagonal wiring in the layout. Some of these embodiments derive the delay cost from an estimate of the wirelength needed to route the nets in the region.
