Kicad is an open source software for the creation of electronic schematic
diagrams and printed circuit board artwork.
with some ideas from freebsd.

PCB is an interactive printed circuit board editor. PCB includes a rats
nest feature, design rule checking, and can provide industry standard
RS-274-X (Gerber), NC drill, and centroid data (X-Y data) output for use
in the board fabrication and assembly process. PCB offers high end
features such as an autorouter and trace optimizer which can tremendously
reduce layout time.

Gnu Circuit Analysis Package
The primary component is a general purpose circuit simulator. It
performs nonlinear dc and transient analyses, fourier analysis, and ac
analysis. It is fully interactive and command driven. It can also be run
in batch mode or as a server. Spice compatible models for the MOSFET
(level 1-7), BJT, and diode are included in this release.

XCircuit is a program for drawing publishable-quality electrical circuit
schematic diagrams and related figures, and produce circuit netlists
through schematic capture. XCircuit regards circuits as inherently
hierarchical, and writes both hierarchical PostScript output and
hierarchical SPICE netlists. Circuit components are saved in and
retrieved from libraries which are fully editable.

Tools for schematic capture, netlist creation, and analog and digital
simulation (log), IC mask layout, extraction, and DRC (wol), simple
chip compilation (wolcomp), MOSIS fabrication request generation
(mosis), netlist comparison (netcmp), data plotting (view) and
postscript graphics editing (until). These tools were used exclusively
for the design and test of all the integrated circuits described in
Carver Mead's book "Analog VLSI and Neural Systems". Until was used
as the primary tool for figure creation for the book. The directory
also contains an example of an analog VLSI chip that was designed and
fabricated with these tools, and an example of an Actel
field-programmable gate array design that was simulated and converted
to Actel format with these tools (example).
These tools were originally written for HP 200 Series ("Chipmunk")
computers, and were later ported to Unix and the X Window System.
Changes:
Examples installed in $PREFIX/examples/qcad.
Uses qt3, so respective patches are now deprecated.
Larger library of premade objects included.
Better font and translation support.
Various bugfixes.

QCad is a free open-source 2D CAD system for *nix. The developers' main
goals are to build a stable, fast and easy to use CAD for everyone. One
doesn't need any knowledge of a CAD program to start working with QCad.
Porters: please make sure you use bsd.port.mk 1.75 or later when
updating ports. That version of the makefile adds all sums. Previous
versions of the makefile will still work for people installing ports.
