Abstract

Logic-level simulation of a digital circuit is commonly effected using a discrete event-driven strategy. We have, alternatively, employed a demand-driven simulation strategy in which simulation speed is improved by avoiding unnecessary component activations and signal evaluations. In this paper we describe the application of this method to the simulation of both logic and timing behaviour. Preliminary results are presented, showing significant performance gains in comparison with event-driven simulation.

Abstract

Numerous physical systems can be described by higher order models including a small time delay. Simpler reduced-order models are needed for control system design and implementation. In this paper, the problem of optimal model reduction for multi-input - multi-output (MIMO) systems in the presence of a small time delay is addressed. The necessary conditions for solving the optimization problem are developed. An example demonstrating the feasibility of the approach is presented.
