在电子产品设计中,电子系统工程师总是希望能找到刚是好或基本刚好满足自己需要的集成电路,以提高电路的集成度和可靠性,降低功耗。因此,专用集成电路设计便应运而生。专用集成电路设计分很多种:一种是全定制集成电路设计。顾名思义,即完全按照某种用途设计的电路,不浪费一点硅片,这种设计方法对于设计人员的水平要求很高,不能有一点差错,而且设计周期长,投资大.只有在大批量生产时才显示其优越性。再一种就是半定制集成电路设计。随着集成电路制造技术的发展,单片集成电路的容量越来越大,制造厂家
In electronic product design, electronic system engineers always want to find just right or just meet their needs integrated circuits, to improve the integration and reliability of the circuit, reduce power consumption. Therefore, ASIC design comes into being. There are many types of ASICs available: one is a fully custom integrated circuit design. As the name implies, that is completely designed according to a certain use of the circuit, do not waste a little silicon, this design method for the level of designers demanding, can not be a bit error, and the design cycle is long, big investment. Only in mass production Only show its superiority. The other is semi-custom integrated circuit design. With the development of integrated circuit manufacturing technology, monolithic integrated circuits more and more capacity, manufacturers
