Abstract
A method and a design automation tool are provided for use in conjunction with designing logic circuits that implement virtual power signals. The method includes providing in a model for each virtual power signal an attribute that distinguishes the virtual power signal from both a logic signal and a power signal. The method also includes one or more circuit analysis, processing and synthesis tool that takes advantage of such an attribute. That is, within the design automation tool, capabilities are provided so that a virtual power signal may be processed in some instances as a logic signal, and at some instance as indistinguishable to a power rail signal or reference.
