Abstract
An automated shielding tool, algorithm, and design methodology for shielding integrated circuits is disclosed herein. This is accomplished by inserting VDD and VSS wire proximate to signal wires on the same metal layer. The noise issues for dynamic circuits is described along with the benefits and costs of wire shielding. The methodology of the shield tool is a systematic approach for dealing with noise due to capacitive and inductive coupling.
