摘要： A method for optimizing electromagnetic interference (EMI) comprising: an EMI analyzing step of analyzing a quantity of electromagnetic interference of an LSI by execution of simulation; a step of selecting an instance with a large quantity of noise in said EMI analyzing step; and a step of adjusting a driving capability of said instance so that it is lowered to an extent that a delay does not occur in a signal timing of said instance selected. In order to optimize the analyzed EMI, the portion for which optimizing is required is extracted, and such a measure as increasing the area where the decoupling capacitance is created is implemented for this portion in a necessary degree. Further, by changing the aspect ratio of the block, changing the block position or changing the cell line, the decoupling capacitance can be easily created at the most efficient inserting position.

摘要： In substrate noise analysis for a semiconductor integrated circuit, it takes long to calculate the amount of current input to the substrate and substrate potential fluctuations in an analog circuit to which the current is propagated in combination with impedance/power supply resistance of the substrate including a large scale RC circuit network. The amount of calculation is reduced in calculating current passed to power supply/ground by adding triangles having areas corresponding to power consumption separately for rising/falling in logical changes in gate level simulation. The amount of calculation is reduced by summing current, interface capacitance, interface resistance, power supply resistance, ground resistance, power supply voltage fluctuations, and ground voltage fluctuations on a basis of block, instance or simultaneous operation. Since the calculation amount is reduced, it takes a shorter period to apply substrate noise analysis. In addition, the elements for calculation are also reduced, and therefore substrate noise analysis can be applied to a large scale semiconductor integrated circuit.

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.
