Research of Genetic Algorithm Applied in Integrated Circuit Design

随着集成电路规模的不断增大,其设计成本越来越高,设计周期也随之变得更长,以遗传算法为代表的现代优化算法提供了一种提升电路设计效率的有效途径。文章从描述具体电路实例入手,阐述了遗传算法应用于模拟﹑射频与数字集成电路设计中的研究现状和成果。针对集成电路设计的不同应用方向,深入探讨了各种电路的拓扑结构,以及算法在编码方式、适应度函数和交叉机理等方面的改进,并对遗传算法在未来集成电路设计中的应用进行了展望。

As the scale of integrated circuits is increasing, it makes higher design costs and longer design cycles. Modem optimization algorithm provides an effective way to improve the efficiency of circuit design, which is represented by the genetic algorithm. From the beginning of the description of the specific circuit,it describes genetic algorithm research status and results in analog,RF and digital IC design. Focusing on different applications, deeply discuss the circuit topology structure and the algorithm improvement in coding method, fitness function and cross mechanism, etc. And finally a perspective for the genetic algorithm application in the future integrated circuit design is dressed out in the paper.
