Help on Choosing a Circuit Simulation Software

Hello Sourav, my recommendation for you is the SPICE simulator LTSPICE/SwitcherCAD. You can download it from the web on Linear Technology's website. The file size is about 5MB.

After the installation you will be asked for a web update. Please update immediately to the latest version.

There is a also user group dedicated to LTSPICE/SwitcherCAD:

There are many more SPICE programs, but LTSPICE is without any limitations and it is 98% compatible to PSPICE on the netlist level. It also has good graphical user interface.

Best Regards, Helmut

There are a LOT of Spice apps out there and taking the time (and bandwidth) to sample them is a Good Thing.

One that I've been using for quite a while and would recommend that you look at is from BeigeBag. They have both a free "lite" mixed-mode and a full-but-time-limited version for download.

See my notes and links to some 60 ECAD programs at

I use Circuitmaker Pro, but there is a limited free version.

Of those I've tried, the best 'unlimited' free version is SwitcherCAD III from LTSpice, which is widely used and praised in these groups.

Hi group.

I am a student of Electronics & Telecommunication Engineering and I need to use some circuit simulation software for my course. I would like to use some free or student version program for Windows/DOS which are easy to use. My main requirements are analog circuit simulation though a mixed mode simulator will be an added advantage. I use a dial-up connection and hence it would be better if the downloadable file-size is reasonable (

B2 Spice? Mine kept crashing. LTSpice is the only one I use now. It's probably the most highly regarded spice program on this group.

Well, I haven't taken my own advice and sampled the current crop of Spices; been using B2 Spice for ages. No more crash-prone than any other Windows app and less so than many. YMMV, shake before using, objects in mirror are larger than they appear, etc...
