Abstract

The paper describes one of the methods to evaluate the design verification progress of logic simulation. In the development of the very large scale general purpose computer HITACHI M-680H/682H, the function test programs designed for the products have been directly used to verify the design in simulation. Test programs establish the definite goal and enable to extensively verify the design. The simulation techniques, which carry out at high speed the very large design described in different levels of abstraction, have developed for this purpose. The method has detected 30% of design errors of M-68X and effectively reduced its development time.
