About OpenSemi
What is the Open-Source Hardware Initiative...
OpenSemi is an initiative to accelerate open-source chip design through the use of an open EDA toolset. The effort begins with a hybrid launch event in Bengaluru, featuring toolchain components from OpenROAD and the Microwatt architecture from the OpenPOWER Foundation.
We are building a neutral, collaborative platform that connects global open hardware projects with academic institutions, VLSI professionals, startup founders and policy makers – starting with a flagship hybrid event in Bengaluru.
-
1
Open architectures. Promote open compute platforms like OpenPOWER A2O with full toolchain and OS support.
-
2
Open EDA & design flows. Enable design teams to go from RTL to GDSII using open flows such as OpenROAD, OpenLane and Yosys, integrated with open PDKs.
-
3
Open silicon prototyping. Leverage open PDKs (e.g., SkyWater SKY130) and global MPW shuttle programs to help teams tape-out real silicon.
-
4
Open collaboration. Bring together students, student communities, research labs, open-source contributors and deep-tech investors under one roof.
Launch Event
Open-Source Hardware Convergence · Bengaluru
