SPICE (simulation program with integrated circuit emphasis) circuit simulation model of resistor module, SPICE simulation method and SPICE simulation device

Abstract

The invention provides an SPICE (simulation program with integrated circuit emphasis) circuit simulation model of a resistor module, an SPICE simulation method and an SPICE simulation device. The SPICE circuit simulation model comprises intrinsic resistor model pieces corresponding to every section of resistance in the resistor module, connection relations among the intrinsic resistor model pieces are as same as that among resistance in the resistor module, each intrinsic resistor model piece comprises an individual resistor, two head resistors and two ground parasitic capacitors, the head resistors and the ground parasitic capacitors are connected with the corresponding individual resistor, the individual resistors are connected with the corresponding head resistors in series, the ground parasitic capacitors are connected with two ends of the corresponding individual resistor. The SPICE circuit simulation model further comprises intersectional parasitic capacitors, and each of the intersectional parasitic capacitors is coupled between end points of the individual resistors of adjacent intrinsic resistor model pieces. By the aid of the SPICE circuit simulation model, relative relation between physical position and electrical property among resistors in a real circuit can be reflected better, and a more accurate circuit simulation result can be obtained.

Description

technical field [0001] The invention relates to the technical field of circuit simulation, in particular to a SPICE circuit simulation model of a resistance module, a SPICE simulation method and a device. Background technique [0002] In the existing SPICE (Simulation program with integrated circuit emphasis) simulation system, when establishing a simulation model of a resistor module with multiple resistors connected in series or in parallel, only multiple single-segment resistor simulation model blocks are used to connect in series or in parallel. However, in such a resistance simulation model, each of the single-segment resistance simulation model blocks can only reflect the physical parameters and electrical properties of its corresponding single-segment resistance, and cannot reflect the relative relationship between the single-segment resistance. Physical location and electrical relationship. [0003] Therefore, it is necessary to propose a new SPICE circuit simulatio...
