Abstract :
A methodology is presented for the physical design automation of array-type analog blocks such as encountered in high-speed data converters and other analog circuits. The approach takes into consideration typical analog constraints and offers full flexibility. A three-step procedure (floorplanning, symbolic routing, and technology mapping), of which the last two steps have been automated in a tool called Mondriaan, solves the layout synthesis problem in a fast and technology-independent way. A set of bus and tree device generators complements the tool set. Industrial-strength examples prove that the proposed solution speeds up the generation of high-quality analog layouts significantly
