The gEDA project has produced and continues working on 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.
NI Circuit Design Suite software improves the PCB design process by integrating capture, simulation, and layout into a single toolchain with NI Multisim and Ultiboard software.
Multisim is industry-standard SPICE simulation and circuit design software for analog, digital, and power electronics in education and research.
