JQM - Java Quine McCluskey for minimization of Boolean functions.
Java Quine McCluskey implements the Quine McCluskey algorithm with Petrick’s Method (or the method of prime implicants) for minimization of Boolean functions. This software can be used both for learning and solving real problems. As learning/teaching tool it presents not only the results, but also how the problem was solved as well as how to use Karnaugh Maps to solve the problem. Up to sixteen functions of sixteen variables can be minimized. A graphical interface is provided for entering and editing the truth table that can be saved and loaded. The results can be exported in HTML format. It generates the Karnaugh Map for educational purpose and the actual truth table from the obtained expressions even when multiple solutions for each function are found. This implementation supports PLC programming, so results can be presented in many forms including Structured Text (ST) and Ladder Diagram (LD) along conventional Boolean expression.

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.

Schematic circuit editor for VLSI and Mixed mode circuit simulation.
Xschem is a schematic capture program, it allows to create a hierarchical representation of circuits with a top down approach . By focusing on interconnections, hierarchy and properties a complex system (IC) can be described in terms of simpler building blocks. A VHDL, Verilog or Spice netlist can be generated from the drawn schematic, allowing the simulation of the circuit. Key feature of the program is its drawing engine written in C and using directly the Xlib drawing primitives; this gives top speed performance, even on very big circuits. I have succesfully managed to simulate complete VLSI projects with this tool, both digital (Verilog / VHDL) and analog (Spice). The user interface is built with the Tcl-Tk toolkit, tcl is also the extension language used to send commands to the program. Schematics can be printed in SVG, PNG, PDF, formats. XSCHEM runs on Linux or other Unix-likes with Xorg server and on Windows with the Cygwin layer and required tools installed.
PCB is a tool for the layout of printed circuit boards. PCB can produce industry standard RS-274X and Excellon NC-Drill format output for submission to board manufacturers.
