SINGLE METAL PROGRAMMABILITY IN A CUSTOMIZABLE INTEGRATED CIRCUIT DEVICE

摘要

A customizable integrated circuit including a substrate (16), a plurality of logic units formed on the substrate and a plurality of metal routing layers formed on the substrate for interconnecting the plurality of logic units. The plurality of metal routing layers includes a first routing layer (14) including a plurality of elongate conductors (20) extending generally in a given direction, a second routing layer (22) including a plurality of transversely extending conductors (24), each adapted for interconnecting a termination of one of the plurality of elongate conductors to a beginning of another one of the plurality of elongate conductors and at least a third routing layer (30), which includes a plurality of local routing conductors, and customizable connections.
