Method for optimizing electromagnetic interference and method for analyzing the electromagnetic interference |
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.
