A solution for determining minimum operating voltages due to performance/power requirements would be valid for a wide range of actual uses. The solution includes a test flow methodology for dynamically reducing power consumption under applied conditions while maintaining application performance via a BIST circuit. There is additionally provided a test flow method for dynamically reducing power consumption to the lowest possible stand-by/very low power level under applied conditions that will still be sufficient to maintain data/state information. One possible application would be for controlling the voltage supply to a group of particular circuits on an ASIC (Application Specific Integrated Circuit). These circuits are grouped together in a voltage island where they would receive a voltage supply that can be different from the voltage supply other circuits on the same chip are receiving. The same solution could be applied to a portion of a microprocessor (the cache logic control, for example).
