ABSTRACT:
In a circuit simulation method, circuit information of an electronic circuit to be simulated is inputted, and whether or not a linear circuit element circuit included in the electronic circuit is passive, is discriminated. For this discrimination, an inductance matrix of the electronic circuit is prepared, and, before a circuit analysis by a circuit simulator, whether or not the inductance matrix is a positive definite is discriminated by obtaining and checking the value of minor determinants of the matrix, and by determining that the circuit is passive if the values of the diagonal items in the matrix are positive definites, and that the circuit is not passive if at least one of the values of the diagonal items in the matrix is not a positive definite. In the latter case, from information of the minor determinants, additional information indicating a cause for non-passivity is derived and outputted.
