TinyCAD is a program for drawing electrical circuit diagrams commonly known as schematic drawings. It supports standard and custom symbol libraries. It supports PCB layout programs with several netlist formats and can also produce SPICE simulation netlists. It is also often used to draw one-line diagrams, block diagrams, and presentation drawings.

Icarus Verilog is an open source Verilog compiler that supports the IEEE-1364 Verilog HDL including IEEE1364-2005 plus extensions.
Simple and intuitive 2D vector drawing for electronics and not only.
A multiplatform vector drawing program with a complete library of electronic symbols. Schematics and drawings are stored in a very compact text format. There is no netlist concept behind the drawings (so no simulation, and this is a choice) but this allows a great graphical flexibility and ease of use, making FidoCadJ the perfect tool for exchange sketches in forum and newsgroup discussions with a few clicks. Drawings can be exported in several graphic formats, such as pdf. Follow the development live on Twitter: https://twitter.com/davbucci

kicad StepUp allows exporting kicad 3D board and comps in STEP AP214
kicad StepUp: a new approach to export kicad board and modules in STEP AP214 (with colors). With kicad StepUp, it is possible to work in kicad EDA with the same component model data available in the STEP AP214 3D format, and obtain a 3D STEP AP214 model of the pcb board and a complete board assembles with electronic modules, to be used for MCAD interchange. The accurate 3D visualization of components on board assembles in kicad 3dviewer, is maintained in the same accuracy and aspect in STEP AP214 format. The kicad StepUp script maintains the usual way to work with kicad, but improves the process to work in a collaborative way with mechanical designers bringing near ECAD and MCAD environments.

Digital Circuits Design and Simulation
Digital Logic Design is a Software tool for designing and simulating digital circuits. It provides digital parts ranging from simple gates to Arithmetic Logic Unit. In this software, circuit can easily be converted into a reusable Module. A Module may be used to built more complex circuits like CPU. The circuit working can be analyzed by using output parts like LEDs, Seven Segment Display and Digital Oscilloscope etc. provided in the software. This Software may be used by professionals, hobbyists and students alike. The teachers may incorporate this software in their courses like Digital Logic and Computer Design, Computer Architecture, Computer Organization and Embedded Systems. In this software, a circuit may be designed using graphical components or may be entered as Sum-of-Product Boolean form.
