XCircuit

XCircuit does not separate artistic expression from circuit drawing; it maintains flexibility in style without compromising the power of schematic capture.

XCircuit doesn't support imports of any other file formats besides PostScript and SPICE.

XCircuit was written and is maintained by Tim Edwards, currently with Efabless Corp., formerly with the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland.

XCircuit was initially written in the summer of 1993 as a drawing program to render circuit diagrams for an undergraduate electrical engineering course in the Johns Hopkins University Whiting School of Engineering Part-time programs.

Since then it has expanded to encompass schematic capture and is used by people all over the world for both presentations and as an EDA (Electronic Design Automation) tool.
