ABSTRACT:
According to the present invention, by setting the logic state of one or more delay signals to appropriate values, the resistive value of a plurality of power supply delay elements throughout an integrated circuit having distributed circuit blocks may be modified to produce desired delay times or pulse width adjustments throughout the integrated circuit. Setting delay signals to desired logic states may be accomplished by a variety of means including forcing test pads to a logic level, blowing fuses, or entering into a test mode.
