Abstract

A programmable logic device (PLD) with a plurality of programmable regions is disclosed. Some of the programmable regions have switch power or ground supplies to allow them to be put into a low-power state in one or more low-power modes. At least one of the programmable regions always remains on during the low-power modes to enable the user to design custom PLD power management logic that may be placed in the always-on programmable region.
