前言 进入八十年代以来,门阵列突然引起了人们的注目,这完全是由市场需求的增加所造成的。在此之前的一段较长的时间内,设备大都是由微型机、存贮器等LSI和用于逻辑电路的SSI、MSI之类的TTL(CMOS)标准IC构成的。为了促使设备的小型化、降低设备价格、提高可靠性和性能,人们逐步认识到,逻辑电路部分也必须LSI化。门阵列是半专用的LSI,利用门阵列的设计思想不仅可以开发原有的LSI和便于保密,而且与全专
Introduction Since entering the eighties, gate array has aroused people’s attention suddenly, this is totally caused by the increase of market demand. For a long time prior to this, most of the equipment consisted of LSIs such as microcomputers and memories, and TTL (CMOS) standard ICs such as SSIs and MSIs for logic circuits. In order to promote the miniaturization of equipment, reduce the price of equipment and improve the reliability and performance, people gradually realize that the logic circuit part must also be LSI. Gate Array is a semi-dedicated LSI, the use of gate array design ideas can not only develop the original LSI and easy to keep secret, but also with the full
