Crosstalk verifying device

A node and coupling capacity selecting portion 4 extracts nodes (NDI) which simultaneously change from a net list (NTL) of a circuit diagram based on an input pattern (IP) and extracts a coupling capacity (CCI) not less than a designated value, and determines a node whose coupling capacity should be...

More Information
Summary:A node and coupling capacity selecting portion 4 extracts nodes (NDI) which simultaneously change from a net list (NTL) of a circuit diagram based on an input pattern (IP) and extracts a coupling capacity (CCI) not less than a designated value, and determines a node whose coupling capacity should be considered from the extraction result, and creats and holds information (ND/CC) of the judged nodes and the coupling capacities thereof. Then, simulation of the selected nodes including the coupling capacities thereof is conducted so that the result of the simulation is displayed in a waveform to thereby enable an efficient and highly precise crosstalk verification.
