最后一章,我们简单介绍在MOS大规模集成电路中已得到广泛采用的一种逻辑设计方法,称其为“可编程序的逻辑阵列”简称PLA。PLA的最大特点是为逻辑设计和版图设计之间提供一个结合点。换句话说,一个系统的逻辑设计完成以后,版画设计也自然地形成了,一个系统的逻辑功能越复杂,利用PLA设计的优越性更大,并且,便于用计算机辅助设计技术来实现设计自动化,除此以外,校核设计错误也十分方便。 In the last chapter, we briefly introduce a kind of logic design method widely used in MOS large scale integrated circuits, which is called “Programmable Logic Array” abbreviated as PLA. PLA’s greatest feature is the logical design and layout to provide a binding point between. In other words, after a system’s logical design is complete, the print design is naturally formed. The more complex a system’s logic functions are, the greater the advantage of utilizing the PLA design and the ease of using CAD technology to design automation. In addition, check design errors are also very convenient.
