Digital Signal Processing algorithms for audio signals. The input can either
be taken from the sound card, or be a locally generated sine wave, white noise
or impulse signal. The output is fed to the sound card, as well as to a virtual
oscilloscope and spectrum analyzer.
The 3.x train of GTKWave has significantly more new featured and bugfixes,
but would require introducing PORTEPOCH to replace cad/gtkwave.
[Timeout on feedback from cad/gtkwave maintainer.]
It features some key concepts like macro recording, workbenches, ability to run
as a server and dynamically loadable application extensions and it is designed
to be platform independent.
Warning: FreeCAD is still in ALPHA state and not in shape for end user usage!

---When you have a large number of or big layout/schematic/TeX files which
have possibly many top cells made by other people, how can you manage
those layout/schematic/TeXs? FH is written for that. It can be useful
up to your imagination or shell programming skill. FH analyses the
hidden hierarchies of those cells and shows you the hierarchy information.

working with superconducting Josephson junction circuits, yet the program

Jspice3 is an adaptation of the Berkeley Spice3f4 program, with added
features. One added feature is a built-in graphical input front end for
schematic capture. While displayed, simulations can be run and data
plotted through this graphical interface.
While not as powerful or as pretty as the Xic graphical interface, it
holds its own in functionality.
A significantly enhanced output plotting capability is provided, and
Jspice3 has enhanced script interpretation capability.

the Tcl/Tk scripting language. The project is open-source (BSD license)
and based upon the NG-Spice source code base with many improvements
Features and Improvements
- Fully Tcl scriptable - installs with 'package require spice' statement
- Hspice syntax (SpicePP).
- GUI interfaces, various (Tk).
- SpiceWish (BLT graph widget)
- BLT (tcl compatible) vectors for storage, manipulation and arithmetic
upon Spice waveforms.
- Xspice additions (Georgia Tech).
- Trigger upon waveform events.
- Spice 'simulator state' save and restore for rapid 'what-if' simulations
(no longer need to re-simulate from the beginning each time a
device value is changed).

The "personal version" is very limited, but it keeps the same format as

partitioning, static mapping, and sparse matrix block ordering.
Its purpose of Scotch is to apply graph theory, with a divide and conquer
approach, to scientific computing problems such as graph and mesh partitioning,
static mapping, and sparse matrix ordering, in application domains ranging from
structural mechanics to operating systems or bio-chemistry.

GPL Cver is a full 1995 P1364 Verilog standard HDL simulator.
It also implements some of the 2001 P1364 standard features
including all three PLI interfaces (tf_, acc_ and vpi_) as
defined in the 2001 Language Reference Manual (LRM).
Verilog is the name for both a language for describing
electronic hardware called a hardware description language
(HDL) and the name of the program that simulates HDL circuit
descriptions to verify that described circuits will function
correctly when the are constructed. Verilog is used only
for describing digital logic circuits. Other HDLs such as
Spice are used for describing analog circuits. There is an
IEEE standard named P1364 that standardizes the Verilog HDL
and the behavior of Verilog simulators. Verilog is officially
defined in the IEEE P1364 Language Reference Manual (LRM)
that can be purchased from IEEE. There are many good books
for learning that teach the Verilog HDL and/or that teach
digital circuit design using Verilog.
