Description

ABSTRACT:
A computer process interconnects logic circuit on an integrated circuit substrate by generating a single softwire statement for each interconnection, and by thereafter utilizing the softwire statements to generate multiple physical layouts for each interconnection. A "softwire statement" is a computer-generated statement which specifies and establishes a route for an interconnection from one terminal of a logic circuit to another terminal as a series of conductive segments which extend in certain directions between relative jog points that are referenced to blockages such as the logic circuits, on the substrate.
