  This article focuses on PSPICE, but most of the parameters and their settings  are common to other SPICE versions like XSPICE NGSPICE IsSPICE HSPICE. The SPICE simulation convergence issues mainly occur for 3 types of problems: Circuit Topology Errors these types of errors are often signaled with precise messages …Read More »

CREATING A SPICE SUBCIRCUIT Want to automatically create subcircuits? The Professional edition of 5Spice 2.0 includes a sophisticated tool to make a schematic into a Spice subcircuit (.Subckt). Later you can modify the schematic and then update the subcircuit with the tool. Creating a subcircuit manually A subcircuit definition contains …Read More »

T. ROBBINS TELSTRA RESEARCH LABORATORIES BOX 249 ROSEBANK MDC, CLAYTON VICTORIA 3168, AUSTRALIA Email: t.robbins@trl.oz.au   Abstract: This article describes an electrical model of a thermalmagnetic circuit-breaker that can accurately simulate characteristic behaviour over a wide range of overcurrents, including operation in the magnetic region. The model has been validated against measured waveforms from both a …Read More »

T. Robbins Telecom Australia Research Laboratories 770 Blackburn Road, Clayton, 3168 Australia   Abstract: The design and analysis of over-current protection for telecommunication DC power systems can be greatly assisted by the use of a computer-aided simulation tool. This article reports on the development of a fuse model for SPICE derived software that can accurately …Read More »
