Abstract
In one embodiment, a method for signal delay in a scan path comprises, in a scan mode, delaying a scan signal in the scan path by propagating the scan signal through a plurality of delay devices coupled in series, wherein a first one of the delay devices is powered by a first voltage, a second one of the delay devices is powered by a second voltage, and the second voltage is greater than the first voltage. The method also comprises, in a functional mode, disabling the delay devices.
