Abstract

A programmable gate array device (10) has a repeating block of circuitry (16) that includes a lowest metal layer. The repeating block of circuitry (16) includes a row of combinatorial blocks (20) and a row of flip flop circuitry (22). A number of metal segments (38) run perpendicular to the row of combinatorial blocks (20). The metal segments (38) are formed in a middle metal layer. A customizable metal layer forms a top metal layer (40).
