Abstract: A programmable logic device (PLD) includes a plurality of segments, a plurality of segment-enable registers, and a configuration controller. Each segment-enable register is arranged to be set to a first value in response to resetting of the PLD. Each segment includes configurable logic that is associated with a respective segment-enable register. In addition, each segment is arranged to enable the configurable logic in response to a second value for the associated segment-enable register. The configuration controller is adapted to program the respective configurable logic in each segment to perform a respective function based on configuration data and to set each segment-enable register to the second value.
