EC300: Circuit Simulators


	*Notes:* (1) Most of these sites have download areas where you can get free evaluation versions of the software. I used to provide a direct link to the download area, but those links tend to break quickly since the company websites get updated frequently. Just click on the company link, and the download area should be easy to find. (2) The blue ellipse indicates packages that I have used myself. Descriptions for the other packages are based on my quick scan of the product’s web page.




	PSpice (MicroSim Corporation)

		PSpice is an enormously popular circuit simulator, probably because it's free evaluation version is identical to the professional version, except for it's built-in circuit size limitation. MicroSim's software is also available at Rose-Hulman's ftp mirror site. Also check out MicroSim's Filter Designer.

	Electronics Workbench (Interactive Image Technologies)

		Electronics Workbench is a neat package since it closely integrates the circuit schematic simulation results. It even allows you to tweak circuit values and flip switches during circuit simulation. A demo version is available, but most of the functionality is disabled. A student version can be purchased for about $60. Look here for additional information about using Electronics Workbench.


	ICAP (Intusoft)

A SPICE-based simulator. Appears to have some nice features for displaying waveforms directly on the circuit schematic.


	SIMetrix (Newbury Technology Ltd.)

A SPICE-based simulator. The web-page description looks promising. The freeware version is completely functional (it doesn't even have circuit size limitations) except for some advanced features found in their main product.


	TINA (DesignSoft)

I’ve read the product literature and it looks like a neat package. One novel aspect about TINA is that is can do symbolic analysis, i.e., enter a circuit schematic and get a Laplace-domain transfer function as a result.


	APLAC

Uses SPICE models, and is also oriented to working with high-frequency (e.g., microwave) components.


	AIM-Spice

Uses SPICE models, graphically displays circuit variables while simulation is in progress.
