Abstract:
1. A method for selectively replacing standard threshold voltage devices with low threshold voltage devices in a digital logic design, comprising the operations of: identifying at least one path in a digital logic design, the at least one path having a plurality of standard threshold voltage devices, the at least one path having a first timing value determined by a timing engine; reverse traversing the path to identify at least one of the plurality of standard threshold voltage devices to replace with a corresponding low threshold voltage device, wherein the low threshold voltage device has a lower threshold voltage needed to activate the device than the standard threshold voltage device; determining, utilizing the timing engine, at least one second timing value for the path associated with replacing the at least one standard threshold voltage device with the corresponding low threshold voltage device; and replacing the at least one standard threshold voltage device with the corresponding low threshold voltage device when the second timing value is less than the first timing value.
