Abstract :
This paper describes a new sea of gates structure, usable for digital random logic, regular arrays, and analog cells. A dedicated design procedure features a full cell-abutment capability, together with channelless routing. Design results are presented for several macroblocs, and compared with other semi-custom approaches. A set of rules is finally presented, which allows an automatic transformation of the sea of gates layout into a topologically equivalent full custom layout, converting semi-custom prototypes to full performance circuits.
