SYSTEM AND METHOD TO PROCESS A VIRTUAL PARTITION CELL INJECTED INTO A HIERARCHICAL INTEGRATED CIRCUIT DESIGN

Abstract:

Aspects described herein relate to physical verification of a design of an integrated circuit to be manufactured on a semiconductor die. One example method involves inserting a virtual partition cell in a parent cell of a layout of a design of an integrated circuit. A child cell of the parent cell has a first portion that overlaps the virtual partition cell and a second portion that is outside of the virtual partition cell. The method also includes creating, by one or more processors, a hierarchy of cells having the child cell and the virtual partition cell descending from the parent cell, wherein the child cell has multiple instances in the hierarchy of cells, and performing a design rule check runset on the parent cell based on the hierarchy.
