orcad III/IV schematic converter 2.9

orcad_convert will dump the contents of an OrCAD L.P. SDT III/IV schematic (.sch) input_file or will convert it to a KiCad eeschema or gEDA gschem text-based schematic format in output_file. orcad_lib_convert will dump the contents of an OrCAD L.P. SDT III/IV library source (.src) input_file or will convert it to a KiCad component library (.lib) output_file or to gEDA symbol files (.sym) in directories having the same name as the input library file.

KiCad

KiCad is an EDA software suite for the creation of professional schematics and printed circuit boards up to 32 copper layers with additional technical layers. KiCad runs on Windows, Linux and Apple OS X and is released under the open-source GNU GPL v2 free of charge.

gEDA 1.8.2

A full GPL'd suite and toolkit of Electronic Design Automation tools. These tools are used for electrical circuit design, schematic capture, simulation, prototyping, and production. Currently, the gEDA project offers a mature suite of free software applications for electronics design, including schematic capture, attribute management, bill of materials (BOM) generation, netlisting into over 20 netlist formats, analog and digital simulation, and printed circuit board (PCB) layout.
