5Spice Analysis Software

Easy to use analog circuit simulation for
the professional circuit designer

5Spice provides Spice specific schematic entry, the ability to define and save an unlimited number of analyses, and integrated graphing of simulation results. Plus easy inclusion of Spice/PSpice® models from a user expandable library. The focus is on analog circuit analysis and design at the component level. Student level MOSFET IC design is also supported but not compatible with HSpice® model libraries.

5Spice has the analysis capabilities needed by experienced circuit designers while remaining easy to use. Choose the standard 2.0 level or new 5Spice Professional for more power and more features.

5Spice uses desktop simulation and local storage to insure the security of your proprietary design. An Internet connection is not required.

"Found 5spice and I love it. Without reading the first word of the instructions, within 1/2 to 1 hour I was simulating and plotting. You have written something really useful and I thank you for your efforts." D.B., an experienced Spice user

"With your program I imported a model (op amp) from Analog Devices and had it in a simulation in 15 seconds. I could not do this in [competitor’s program] (and I tried) in a whole day!" B. Labitt

In the lab

"I must say this is the best spice program I’ve ever used and I’ve been doing circuit analysis since the early 1960’s." J. Gersbach         more comments
