Circuit Design and Simulation Project using eSim

Invitation to participate in Circuit Design and Simulation Project using eSim

The FOSSEE (Free and Open Source Software for Education) project based at lIT Bombay has initiated a Circuit Design and Simulation Project using esim (an open source EDA tool for circuit design, simulation, analysis and PCB design).

Interested candidates can take any solved electronic circuit from any source and redesign it using eSim and submit it to us. Candidates will be rewarded with certificates and honorarium after a review process. These circuits will also be published on our website under an appropriate open source license.
