FreeRouting can be used together with all host PCB design software systems containing a standard Specctra or Electra DSN interface. It imports .dsn-files generated by the Specctra interface of the host system and exports Specctra session files. There exists also an interface to Cadsoft-Eagle. There are three modes for routing traces: 90 degree, 45 degree and free angle. The interactive router is production stable and unsurpassed in its free angle capabilities.
Oregano is a graphical software application for schematic capture and simulation of electrical circuits. The actual simulation is performed by the ngspice or Gnucap engines. It is similar to gEDA and KTechlab. It makes use of GNOME technology and is meant to run on open source Unix environments like Linux or FreeBSD.

XCircuit is a Unix/X11 (and Windows, too, with an X-Server running) 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. XCircuit does not separate artistic expression from circuit drawing; it maintains flexibility in style without compromising the power of schematic capture.
