标准单元是在门阵列和CAD技术基础上发展起来的一种新一代半导体集成电路,它介于门阵列电路和全定制电路之间,属于半定制电路范畴。 何谓标准单元。 标准单元是指对预先设计的单元(Cell)进行组合,然后设计出整个芯片的大规模集成电路,所谓单元则是指能完成某种功能的一种逻辑电路。 标准单元一般可分为多单元型(Polycell)和积木式部件型(Building Block)[或称 The standard cell is a new generation of semiconductor integrated circuit developed on the basis of the gate array and the CAD technology. It is between the gate array circuit and the fully customized circuit and belongs to the semi-custom circuit category. What is a standard unit? Standard cell refers to the pre-designed cell (Cell) combination, and then design a large-scale integrated circuit chip, the so-called unit is able to accomplish some kind of logic circuit. Standard unit can be divided into multi-unit (Polycell) and building blocks (Building Block) [or
