EFFICIENT LAYOUT STRATEGY FOR AUTOMATED DESIGN LAYOUT TOOLS

摘要

A method is described that involves automatically laying out a circuit structure in software by describing in a software environment the placement of a gate structure relative to a diffusion region. The gate structure has: 1) a pair of gate fingers that project over the diffusion region along a y axis; and, 2) a landing area for receiving multiple contacts from a metal 1 layer. The method also involves running a pair of source fingers at a metal 1 layer over the diffusion area and along the y axis. The pair of source fingers are outside the pair of gate fingers and are an extension of a metal 1 source wire running along an x axis. The method also involves placing a metal 1 gate pad layer over the landing area.
