Description

ABSTRACT:
Within a computer automated tool, a method of physical circuit design can include assigning initial locations to components in the circuit design and determining an initial routing of connections between components in the circuit design using an overlap mode. The method also can include determining timing critical connections and selectively relocating components with at least one timing critical connection prior to performing a detailed routing of the circuit design.
