Noise countermeasure determination method and apparatus and storage medium

A noise countermeasure determination apparatus comprising:

• a recommended circuit information calculating section calculating recommended circuit information considered to minimize a noise by use of at least one formula, based on input circuit information amounting to at least one net of a target circuit which is to be subjected to a noise analysis;
• and
• a noise countermeasure determination section comparing the input circuit information and the recommended circuit information, and determining a differing portion of the recommended circuit information differing from the input circuit information, as noise countermeasures.

A computer-readable storage storing a program for controlling a computer to determine noise countermeasures, by:

• calculating recommended circuit information considered to minimize a noise by use of at least one formula, based on input circuit information amounting to at least one net of a target circuit which is to be subjected to a noise analysis;
• and
• comparing the input circuit information and the recommended circuit information and determining a differing portion of the recommended circuit information differing from the input circuit information, as noise countermeasures.
