Engineering & Scientific Software - Circuit Design & Simulation
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.

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.
