ABSTRACT:
A gate array architecture is disclosed that utilizes significantly less silicon area than the prior art. The core cell includes a four transistor arrangement in which a substrate tap is located adjacent to the transistor pair. This provides for a more "symmetric" cell array than those in the prior art. Through the placement of the taps outside of the transistors the power line connections can be routed in a simple and efficient manner. The architecture includes an extension portion in the contact region of the cell to further reduce wiring complexity. In addition the gate array architecture mirrors pairs of transistor columns to allow for the sharing of substrate taps between pairs of columns. This mirroring feature further reduces routing complexity. The architecture further includes a plurality of probe lines that are located within the architecture to facilitate testability of the outputs of the architecture.
