You may also copy files and images into other Windows compatible programs (e.g. Multisim includes a schematic capture 'front-end', which means that you can 'draw' a circuit diagram on-screen and then perform your analyses directly from this 'captured' schematic. Once optimised, the circuit may be built and tested against these predicted results with a considerable reduction in design cost overheads. The circuit under test can be modified on the computer to obtain revised response predictions. Computer-based circuit analysis is a powerful alternative to 'bread-boarding' and extensive circuit measurements. Multisim uses 'SPICE-like' models to describe the behaviour of all network elements.

The first analogue simulation program SPICE was developed at the University of California at Berkeley in the early 1970s and has become a de facto standard in the area of analogue simulation. These programs all calculate the voltages and currents of a circuit under a variety of different conditions. Multisim is an analogue and digital circuit simulator that has similarities with Altium Designer, TINA and PSpice. Chapter 2 describes an introductory tutorial to Multisim. This initial chapter provides a basic overview of circuit simulation. This guide introduces some of the main features of the Multisim analogue and digital simulation software which is currently installed on PCs in the School of Engineering and Technology. ġ.2 Circuit Simulation 1.2.1 DC Analysis 1.2.2 AC Analysis 1.2.3 Transient Analysis 1.2.4 Network Topology 1.2.5 Branches & Nodes 1.2.6 Active Devices The National Instruments website contains full details of Multisim A student version can be purchased (version 13).
