Automatic development of circuit and interconnection equations on the basis of topology and library of network components: SPICE approach

Abstract

The modules for processing of interconnection specifications which are provided in an input file of circuit analyzer were developed. A software package for creation of appropriate computer models on the basis of topology and library of network components was also constructed and implemented using SPICE program. A computer program, called LSPICE, has been developed by combining SPICE numerical techniques and the modal analysis of coupled transmission lines. This program can be used for simulating the transient response of networks containing coupled lossless transmission lines. Several example networks have been simulated using this program. The results have been compared with those generated by the circuit simulator program called UANTL. The LSPICE has several advantages over UANTL and SPICE in simulating the transient response of network containing coupled lossless transmission lines. A description of LSPICE and a summary of the results of numerical experiments are included.
