This website is the repository for the suite of open-source EDA (Electronic Design Automation) tools including Magic, IRSIM, Netgen, PCB, and XCircuit. These tools are all provided for free under the GNU Public License (GPL). Open Circuit Design is committed to keeping open-source EDA tools useful and competitive with commercial tools.
Magic, the VLSI layout editor, extraction, and DRC tool.
XCircuit, the circuit drawing and schematic capture tool.
IRSIM, the switch-level digital circuit simulator.
Netgen, the circuit netlist comparison (LVS) and netlist conversion tool.
PCB, the printed circuit board layout editor.
Digital Flow – A Digital Flow using Open Source EDA Tools.
Qrouter version 1.0 multi-level, over-the-cell maze router.
The most important characteristic powerEsim is that it provide a virtual laboratory environment for engineer to verify and fine tune their design. Experience engineer use it to optimize their design by saving a lot of time than in real bench.
The circuit simulator is a combination of iteration, equation based apporoach and time step integration. The circuit is defined by non-linear equations and the simulator will first solving the switching condition solution for t=infinity by bracketed iteration, then fine step of point by point results will be generated by those equations for V, I and loss analysis.
The world of science and engineering is filled with signals: images from remote space probes, voltages generated by the heart and brain, radar and sonar echoes, seismic vibrations, and countless other applications. Digital Signal Processing is the science of using computers to understand these types of data.
