早在六十年代的中、后期,就有人提出互连是LSI问题的中心,并围绕解决成本、研制周期、设计灵活性、芯片面积的利用、功能密度以及如何充分利用成批加工技术等问题,提出了多种有关互连的方案。其中就有多单元法和微矩阵法,它们的设计思想与当前流行的标准单元库法和门阵列方法很相似。 As early as the mid-to-late 1960s, it was suggested that interconnection was at the heart of LSI’s problems and that issues such as cost, development cycle, design flexibility, chip area utilization, functional density, and how to make the best use of batch processing techniques , Proposed a variety of programs related to interconnection. Among them are the multi-cell method and the micro-matrix method. Their design ideas are very similar to the current popular standard cell library and gate array methods.
