The firm's MS-Master design methodology for submicron mixed-signal ASICs touts successful first-pass silicon rates of 90% and higher, it's claimed. The methodology is based on behavioral models that are generated from Spice simulations and verified to produce working silicon on the first pass. The result is drastically shorter design simulation times and products that get to market faster. The methodology is a unified process that uses stable, commercially available tools with selected add-ons. It performs true mixed-signal ASIC design in a familiar digital environment. Deep-submicron designs with from 10,000 to one million gates can be created with either small or large amounts of analog circuitry.
