Abstract

Integrated circuits and methods use a margin test voltage generator that is powered at a first power supply voltage to generate a second power supply voltage that has a magnitude that is less than the magnitude of the first power supply voltage. During a low supply voltage margin test, a first logic circuit is powered at the first power supply voltage while a second logic circuit, which is the subject of the test, is powered at the second power supply voltage. As a result, the first power supply voltage may remain at a sufficient magnitude to reliably power other devices or components that are not undergoing the low supply voltage margin test.
