A unified macro CAD system

In order to succeed in the ASIC business, time to market for a new product is a high priority. To increase productivity and to decrease human error, a macro CAD system has been developed. The system is an integrated piece of software that consists of eight separate modules operating under a run-time system controller. A test vector set representing all possible input patterns is generated and simulated from both digital and analog standpoints. The results are compared to verify logic functionality and then used to extract critical timing parameters.<>
