Method to perform secondary-PG aware buffering in IC design flow

Abstract:

A system to generate a design of an integrated circuit, the system comprising a memory and a processor, the processor to define a plurality of voltage area regions (VARs), based on an availability of one or more of a primary power source and one or more secondary power sources. The processor further to constrain placement and/or routing of an element in the design of the integrated circuit within a voltage area region of the plurality of voltage area regions defined by secondary power/ground (PG) constraints based on power requirements of the element.
