Electric circuit evaluation method

摘要

The electric circuit evaluation method according to the present invention comprises: a step for finding a malfunction power frequency property, in which the magnitude of a critical noise signal at which a designated electric circuit causes a malfunction is represented by the power injected into the designated electric circuit; and a step for finding a malfunction current frequency property, in which the magnitude of the critical noise signal at which the designated electric circuit causes a malfunction is represented by a current (I_LSI) flowing to a predetermined portion of the designated electric circuit, and a malfunction voltage frequency property, in which the magnitude of the critical noise signal at which the designated electric circuit causes a malfunction is represented by a voltage (V_LSI) occurring between predetermined points of the designated electric circuit, both of which properties found from the malfunction power frequency property.

1. An electric circuit evaluation method comprising the following steps:
a step for finding a malfunction power frequency property, in which the magnitude of a critical noise signal at which a designated electric circuit causes a malfunction is represented by the power injected into the designated electric circuit; and a step for finding a malfunction current frequency property, in which the magnitude of the critical noise signal at which the designated electric circuit causes a malfunction is represented by a current flowing to a predetermined portion of the designated electric circuit, and a malfunction voltage frequency property, in which the magnitude of the critical noise signal at which the designated electric circuit causes a malfunction is represented by a voltage occurring between predetermined points of the designated electric circuit, both of which properties being found from the malfunction power frequency property.
