Abstract
A programmable logic device (PLD) includes a non-volatile memory, a configuration memory, and a control circuitry. The control circuitry couples to the non-volatile memory and to the configuration memory. A set of voltages are derived from the outputs of the control circuitry, and are applied to circuitry within the PLD.
Claims23
A programmable logic device (PLD), comprising:
- a non-volatile memory;
- a configuration memory;
- and
- a control circuitry coupled to the non-volatile memory and to the configuration memory,
- wherein a set of voltages are derived from outputs of the control circuitry, and
- wherein the set of voltages are applied to circuitry within the programmable logic
- device (PLD).
A programmable logic device (PLD), comprising a set of circuits configured to allow measuring delay characteristics of circuitry within the programmable logic device, the set of circuits comprising a set of transistors with varying ratios of a width of a P-type transistor to a width of an N-type transistor, wherein power consumption of the programmable logic device is optimized by using a model derived from the delay characteristics measured using the set of circuits.
