Semiconductor device simulation apparatus as well as method and storage medium storing simulation program thereof

摘要

In device numerical analysis by a computer, in the case of analysis involving an external circuit, much better initial values are given so that calculation time is shortened. A device simulation apparatus 10 includes: a presumed potential designation unit 12 for a user to designate presumed potentials in device electrode nodes; a physical quantity initial value setting unit 14 to acquire a physical quantity by analyzing the above described presumed potentials to set the above described physical quantity as an initial value of a physical quantity at internal nodes in the device; a potential initial value setting unit 16 to set an initial value of potential at nodes of the external circuit based on the above described presumed potential; and a device analyzing unit 18 to analyze a device involving an external circuit with the above described set initial values. Usage of device electrode node potentials presumed by the user makes better initial values available.
