The yorktown simulation engine: Introduction

Abstract

The Yorktown Simulation Engine (YSE) is a special-purpose, highly-parallel programmable machine for the gate-level simulation of logic. It can simulate up to one million gates at a speed of over two billion gate simulations per second; it is estimated that the IBM 3081 processor could have been simulated on the YSE at a rate of 1000 instructions per second. This is far beyond the capabilities of existing register-level software simulators. The YSE has been designed and is being constructed at the IBM T. J. Watson Research Center. This paper introduces the YSE and describes its top-level architecture.
