Abstract
A programmable logic device (PLD) provides voltage identification (VID) codes to a voltage regulator module having VID capabilities. The voltage regulator module generates supply Vdd and/or body bias Vbb voltages according to a selected VID code. The value of the supply Vdd and/or body bias Vbb voltages generated and applied to the PLD determine the operating characteristics of the PLD. The VID codes can be provided and stored in various ways: by an addressable lookup table (LUT) integrated with the PLD, by a memory device in which the VID codes are transferred from an external memory. The VID codes may also be self-generated by auto-detect circuitry integrated with the PLD. The ability to select a particular VID code for each individual PLD allows the user to optimize operational characteristics of the device to satisfy power and/or performance requirements.
