Abstract
As VLSI technology advances, designers can pack larger circuits into a single chip. According to the International Technology Roadmap for Semiconductors, in the year 2005, VLSI circuit technology will produce chips with 200 million transistors in total, 40 million logic gates, 2 to 3.5 GHz clock rates, and 160 watts of power-consumption. Recently, Intel announced that they will produce a billion-transistor processor before 2010. However, current design methodologies can only handle tens of millions of transistors in a single design. In this thesis, we focus on the problem of simulating large digital devices at the gate level. While many software solutions to gate-level simulation exist, their performance is limited by the underlying general-purpose workstation architecture. This research defines an architecture that is specifically designed for gate-level logic simulation that is at least an order of magnitude faster than software running on a workstation. We present a custom processor and memory architecture design that can simulate a gate level design orders of magnitude faster than the software simulation, while maintaining 4-levels of signal strength. New primitives are presented and shown to significantly reduce the complexity of simulation. Unlike most simulators, which only use zero or unit time delay models, this research provides a mechanism to handle more complex full-timing delay model at pico-second accuracy. Experimental results and a working prototype will also be presented.
