This paper proposes two techniques for improving the accuracy of gate-level power analysis for system-on-a-chip (SoC). (1) The creation of custom wire load models for clock nets (2) The use of layout information (actual net capacitance and input signal transition time) The analysis time is reduced to less than one three-hundredth of the transistor-level power analysis time. The error is within 5% of that of a real chip, (the same level in transistor-level power analysis) if technique (2) is used. The analytical error between technique (1) and (2) is within 1%
