METHOD FOR DETECTING HIGH IMPEDANCE

摘要

PROBLEM TO BE SOLVED: To provide a method for detecting high impedance capable of detecting a through-current in a simulation circuit without modifying the simulation circuit during simulations of an analog circuit including transistors. SOLUTION: The method includes a process for analyzing whether or not the condition for entering a high-impedance state exists for all nodes in the circuit. Also, the method includes a process for analyzing whether or not the condition for a through-current generated due to the high-impedance state exists for all the nodes in the circuit. The method also includes a process for detecting whether or not the condition for entering the high-impedance state and the condition for a through-current generated due to the high-impedance state will be met during execution of the simulations.
