Open Source C++ Electronic Design Automation (EDA) Software for Windows

Qucs is a circuit simulator with graphical user interface. The software aims to support all kinds of circuit simulation types, e.g. DC, AC, S-parameter, Transient, Noise and Harmonic Balance analysis. Pure digital simulations are also supported.

Electronic circuit simulator. Simple environment to run and debug firmware for AVR 8-bit microprocessors. Able to run arduino firmware. Internally this program uses the open source Simavr AVR Processor Simulator (https://github.com/buserror/simavr) and wraps all its functions in a GUI shell. Setups for firmware debugging scenarios can be created dynamically. Able to run 16MHz MCU with decent set of external parts in real time. In particular this can be used for development of CNC firmware in conjuction with its CAM frontend without access to the real hardware. For Linux and Windows systems. Please visit wiki pages (https://sourceforge.net/p/simutron/wiki/Home/) for instructions

PikLoops is a simple KDE program used to generate assembly time delays for Microchip microcontrolers using Microchip instructions.

Qlogico is a digital circuit simulator. True table, manipulation of boolean expresions, schematic capture and simulation, finite state machines, table of transitions, VHDL.
