Abstract: A method for simulating a power consumption associated with a circuit. Once a netlist describing the circuit and an input stimulus for the netlist are obtained, the netlist is partitioned into multiple circuit blocks. Circuit logic models (CLMs) implemented in a hardware description language (HDL) are then obtained for the multiple circuit blocks and a logic netlist is generated from the multiple CLMs. A power vector for a CLM corresponding to a circuit block is calculated using a logic simulator inputting the logic netlist and the input stimulus. Further, a power consumption value is calculated for the circuit block using a circuit simulator and the power vector. The power consumption associated with the circuit is calculated based on the power consumption values for various circuit blocks.

Abstract: A method for simulating a power consumption associated with a circuit. The method includes: obtaining a netlist describing the circuit and an input stimulus for the netlist; partitioning the netlist into multiple circuit blocks; obtaining multiple circuit logic models (CLMs) implemented in a hardware description language (HDL) for the multiple circuit blocks; generating a logic netlist from the multiple CLMs; calculating, using a logic simulator inputting the logic netlist and the input stimulus, a power vector for a CLM corresponding to a first circuit block; calculating, using a circuit simulator and the power vector, a first power consumption value for the first circuit block; and calculating the power consumption associated with the circuit based on the first power consumption value.
