摘要： Based on design data of a semiconductor integrated circuit, an impedance related to a power supply wire is calculated, and based on the calculated impedance, a frequency characteristic of power supply noise is analyzed. In calculation of an impedance, an impedance between power supplies which are different in potential, e.g., a main power supply and a ground, may be calculated. Alternatively, an impedance between power supplies which are substantially the same in potential, e.g., a main power supply and an N-well power supply, may be calculated. The calculated impedance includes a wire capacitance between power supply wires, a substrate resistance, an impedance of a package connected to the power supply wires, and so on. Thus, it is possible to provide a method for analyzing power supply noise of a semiconductor integrated circuit, which can be executed at an early stage of a design process with a small amount of calculation.

摘要： In optimizing a necessary capacitance of a semiconductor integrated circuit, the capacitance optimization can be achieved with higher precision by optimizing an IR drop (voltage drop) while considering dynamically a cell activation rate. In other words, in estimating a power-supply capacitance inserted to suppress a voltage fluctuation of the power supply, an areal demerit can be reduced by reducing a necessary capacitance component as a whole while considering a cell activation rate in the circuit or by selecting the capacitance required to supplement only temporal portions whose power-supply fluctuation is wide after the estimation of a cell operating timing. Also, the process can be conducted in a short time at the early stage of design by using a wiring load model at the time of capacitance estimate.
