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.

Filter and Coupling
Matrix Synthesis Software. Get an overview of main filter parameters in seconds, without complex circuit models
and modeling. Our Coupling Matrix Synthesis™ software facilitates synthesis of N+2 coupling matrices for Chebyshev
bandpass filtering functions, with arbitrary finite-position transmission zeroes. The software also facilitates
coupling matrix synthesis through topology matrix definition. It gives a fast and accurate overview of insertion
loss, isolation, group delay and coupling coefficients versus filter order, return loss and transmission zero positions.
The software allows placement of complex transmission zeroes, which opens up for group delay shaping and analysis.

points on the response curve to where you would like them to be, and the program automatically adjusts your RLC
components to accommodate the curve.

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.
