Engineering & Scientific Software - Circuit Design & Simulation
Manufacturers & Services
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.

Product distributors and sales representatives are not listed (they have their own page). This helps guarantee that each
listing offers a unique product or service. NOTICE: I am no longer adding hyperlinks due to so many companies asking to

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.

A slick Java-based applet (which
means it works on any platform) that allows you to build RLC circuits with drag-n-drop interface and plots
results on a Cartesian (Bode) or Smith Chart. "What is so slick about it," you ask? The truly slick part is
that you can drag 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.
