Zusammenfassung:A method of calculating power usage of a lookup table (LUT) implemented on a programmable logic device can include determining input power usage of the LUT and determining output power usage of the LUT. The method further can include determining internal power usage of the LUT. Data rates, LUT configuration, and node capacitance information can be used in determining input, output, and internal power. A measure of power usage for the entire LUT can be provided by summing the input power usage, the output power usage, and the internal power usage.
