Circuit Analysis

A power estimation tool (1) receives as inputs a netlist (2) for a circuit and a library (3) of power models having values for power consumption of circuit components. It stores estimated values for components which are not randomness-preserving, and accurate values for components which are randomness-preserving. A component is randomness- preserving if input and output fixed length strings are random, in which each element in a sequence has an equal probability to occur. The values in the library (3) for randomness-preserving components are for small, low-level, components and are exact. The latter values ma for example be provided in specifications for standard low-level components such as XOR gates. The tool (1) feeds as an output average power consumption for the whole target circuit into a circuit design process (4). The input to the design process may be used in iterative cycles in which there is dynamic change of a netlist so that a target circuit can be optimized for power efficiency.
