Evolving Optimal Multi-Objective Hardware Using Strength Pareto Evolutionary Algorithms.

In this paper, we focus on engineering Pareto-optimal digital circuits given the expected input/output behaviour with a minimal design effort. The design objectives to be minimised are: hardware area, response time and power consumption. We do so using the Strength Pareto Evolutionary Algorithms. This is novel application of multi-objective optimisation to circuit design. The performance and quality of the circuits evolved for some benchmarks are presented then compared to those of single objective genetic algorithms as well as to the circuits obtained by human designers. We show that the evolutionary hardware is far better with respect to all objectives than those designed using traditional methods.
