With this software, you can set ranges for various circuit components, tell the program what you want to optimize, and it will compute the best values for you. We frequently use Spice when we are too lazy to do the math required to pick an optimal set of values.

One nice touch is that you can view a simulation and interactively change component values and watch the results update right away. You can, however, select “large toolbar” on the Options | Preference menu, which will help. On a big monitor, you might want to use Winecfg to set a higher DPI setting, although the toolbar icons are fixed in size which is a little inconvenient. The 64-bit one would probably work with a little effort. There are also over 2,000 standard digital parts including all the usual 7400 families, CD4000 CMOS, and even ECL.Īs a bonus, we tried it under Wine and it worked well - at least the 32-bit version. There are also quite a few examples provided. It can also export Spice files if you want to use another engine or share designs with other Spice users.
It can also read just about any regular Spice or IBIS model. The number of models supported for active devices is impressive and includes some very recent MOSFET models, not just the old standard models. Have a look at the brochure and you will see this is a pretty serious piece of software. There’s a built-in designer for active and passive filters. The simulator boasts a multipage schematic editor, native robust digital simulation, Monte Carlo analysis, 33,000 parts in its library, worst-case and smoke analysis, Smith charts, and it can even incorporate spreadsheets. You may be thinking: why use another closed-source simulator? Well, all the simulators have particular strengths, but Micro-Cap does have very nice features and used to retail for about $4,500.

However, there is a new free option after the closing of Spectrum Software last year: Micro-Cap 12. If you are looking for simulation software, you are probably thinking LTSpice or one of the open-source simulators like Ngspice (which drives Oregano and QUCs-S), or GNUCap.
