This project aims to produce an open-source electronic design automation (EDA) toolkit, including a schematic editor, a mixed-mode circuit simulator, accurate models for several devices and a PCB editor with autorouting capability. The code is designed in such a way that it can be used as a component in simulating complete systems. We use the Agar GUI toolkit. Since we have not yet decided on an official name, we call it "Agar-EDA" for now.

Unlike many circuit simulator packages, Agar-EDA is not based on SPICE. Agar-EDA has it has its own circuit simulator built from scratch. We use the Modified Nodal Analysis (MNA), a technique that is well-suited to both the symbolic and numerical analysis of complex circuits.

The Agar-EDA project is intended to complement the existing open-source simulators (such as SPICE or the excellent Qucs), since its goal of achieving real-time simulation places it in another category. Real-time simulation entails different problems (e.g., the user can interact with the circuit in real-time, the simulation may be receiving or generating signals through external devices, etc).

Agar-EDA is written in ANSI C, and is portable to the many platforms supported by Agar. The Agar-EDA source code is freely usable and re-usable by everyone under a revised BSD license.

Because Agar-EDA is free software, you are encouraged to make it more useful. Send the maintainer (vedge at hypertriton.com) your patches, suggestions, requests and affronts without inhibitions.
