Circuit simulators listed here apply primarily to those used for analog, RF, and microwave circuits. Designing high frequency circuits for first-pass success requires a very high level of sophistication by the software. It must contain component models (including substrates and enclosures) that accurately compute values that take into account the many parasitic effects of lead inductance, interwinding capacitance, resistance of the component, etc. Generally, price correlates directly to the capability of the software.

Symbolic analysis for linear circuits. This Freeware takes spice-like net lists as input and computes symbolic z, y, h, g, abcd, ABCD, s and f two-port parameters. Any selection from these two-port parameters may be specified for output. The output is in the form of rational functions. Your favorite circuit elements: R, G, L, C are usable, two-port active and passive elements: gm (vcis), rm (icvs), U (vcvs), B (icis) , GY (gyrator), M (mutual inductance), O (nullor type opamp) are available. Any component may optionally be assigned a numeric value. The furnished program executable runs on the dos command line accepting input from stdin and sending output to stdout. Detailed help including simple input examples, such as Sallen-Key active filters is output with an h in the input stream. Definitions of the two-port parameters, netlist definitions, and references to the method of analysis are also in the help output. The C source, ready to compile with gcc is also furnished, as is a help file.
