SPICE Simulation Fundamentals

Overview

The National Instruments SPICE Simulation Fundamentals Series is your free resource on the Internet for learning about circuit simulation. The series is a set of tutorials and information on SPICE simulation, OrCAD pSPICE simulation, SPICE modeling, and other concepts in circuit simulation.

The series is divided among a number of in-depth detailed articles that offer HOW TO information on the important concepts and details of SPICE simulation.

Circuit simulation is an important part of any design process. By simulating your circuits, you can detect errors early in the process, and avoid costly and time-consuming prototype reworking. You can also easily swap components to evaluate designs with varying bills of materials (BOMs).

NI Multisim is an example of an easy-to-use, powerful, and flexible SPICE simulation environment that allows educators to teach circuit theory, and engineers to quickly design topologies.

SPICE Simulation Models

 SPICE Simulation Models One of the most fundamental facets of SPICE simulation is a set of accurate models of the components used in any given circuit. There are literally millions of different SPICE models available. Learn about the basics of a SPICE model, model makers, and where to look for vendor-specific models of components. Learn more >>

Basic SPICE Simulation Model Parameters

 Basic SPICE Simulation Model Parameters Intrinsic to SPICE is the ability to model basic and more advanced single element real and ideal components. Read this tutorial to learn the basics about the various models that are available in SPICE. Learn more >>

 Advanced SPICE Simulation Model Parameters The native SPICE models have a number of very specific parameters that control how the simulation model will behave under varying circumstances. For example, you can change the temperature coefficients for a resistor to make your simulation more closely match a vendor’s component.

SPICE Simulation Options

 SPICE Simulation Options Simulations can be accurate because of the quality of the SPICE models used and the simulation options. Parameters such as relative tolerance (RELTOL) and timestep can have a drastic affect on the results produced by the SPICE simulator. This article gives you detailed information on a number of the many options available and what effect changing them will produce. Learn more >>
