Technology- and power-supply-independent cell library

The authors present a novel principle for the design of digital CMOS cell libraries. All the cells are made of branches (1 to 3 MOS in series), providing the possibility of describing only a few very simple branch models that can be parameterized by the power supply and by different technologies. All the cells are exclusively made of branches that contain one or several transistors in series connected between a power line and a logical node. This concept was originally used for a gate-matrix layout system.<
