Background and Motivation

The design and verification of integrated circuits (ICs) traditionally rely on expensive proprietary tools and closed foundry ecosystems. This creates a barrier for students, researchers, and startups, particularly in developing regions, who wish to explore VLSI design.

To address this challenge, FOSSEE, IIT Bombay, has developed eSim, an open-source EDA tool that enables schematic design, simulation, and PCB development. eSim is intended to democratize access to electronics design by offering a free and customizable alternative to commercial EDA tools.

In parallel, IHP Microelectronics, Germany, has taken a pioneering step by releasing the SG13G2 PDK under an open-source license. This BiCMOS technology enables high-frequency analog, RF, and digital circuit design at the 130 nm node—something previously accessible only through expensive, closed-access channels.

By combining eSim with the IHP SG13G2 PDK, this marathon creates a rare opportunity for students, faculty, and enthusiasts to:

• Gain hands-on experience with a real-world PDK
• Design and simulate analog, digital, and mixed-signal circuits using only open tools
• Develop practical skills that align with industry and research requirements
• Contribute to the growing global movement for open-source silicon

The marathon fosters capacity-building in VLSI using open infrastructure, in line with national and global educational goals.
