Analysis and design of on-chip power grids are complex problems. A typical grid consists of hundreds of millions of transistors that act as current consumers. Typical algorithms for power grid analysis or power grid automatic design, model the current consumers, namely the CMOS logic gates, as ideal current sources. In this study we offer a new methodology for modeling the power-consuming gates on...
Current propagation within a lightly doped substrate is approximated with a half-ellipse to efficiently estimate substrate resistances. As opposed to existing work, the proposed model contains only one fitting parameter. Compact models are also developed to determine the isolation efficiency of several commonly used structures such as a guard ring and triple well. The accuracy of these models is verified...
