QuarlSIM is a software suite of free open source Electronic Design Automation tools maintained and developed by student at Chalmers University. These tools are used for electrical circuit design, schematic capture, simulation, prototyping, and production
CircuitSmith is to be a comprehensive electronic design package being developed in Java which will include schematic capture, printed circuit board layout and any other features which I (and hopefully others) can be bothered to program.
Virtual electronic circuit simulation with JAVA based schematic entry and wave viewer, based on (Berkeley) SPICE, for any OS/Server/Browser configuration.
Due to missing public feedback for over one year its status is set to INACTIVE (1/2004) - sorry.
