CMOS/SOS automated universal array
F. Borgini, Barry Suskind · IEEE Journal of Solid-State Circuits · 1981
The CMOS/SOS automated universal array (AUA) is a new, minimum-cost approach for generating custom LSI devices. This is achieved by implementing a compatible automatic placement and routing program which automatically generates a single, customized interconnect metal level that defines the desired logical function. The AUA topological design is specifically configured to be compatible with automatic layout techniques, and as a result the AUA system can guarantee 100 percent connectivity with greater than 90 percent gate utilization for any random-logic application. The CMOS/SOS AUA is an equivalent 800-gate design consisting of a repetitive pattern of 640 basic internal cells and 62 basic peripheral cells for I/O functions, as well as a variety of special cells located in the periphery which meet the needs of most digital applications that may be encountered. Depending on the logic design complexity and computer used, an artwork tape depicting the metallized layout pattern can be generated within 24 h.
