Democratizing Chip Design with IBM’s OpenPOWER Microwatt Core, FPGA Platforms, and OpenROAD EDA
In the world of computing, chip design has traditionally been a complex, resource-intensive field, reserved for a few companies and requiring significant investment. But thanks to open-source initiatives, we’re now on the cusp of a new era where anyone—from students and researchers to startup founders—can explore, design, and prototype their own chips. The combined power of IBM’s OpenPOWER Microwatt core, FPGA platforms, and OpenROAD EDA tools makes this a reality, giving everyone the tools to become chip designers.
This blog explores how these open-source tools work together to democratize chip design and how you can get started. We'll also provide a typical agenda for a hands-on workshop that introduces these tools in a single day.

The Cornerstones of Open-Source Chip Design
1. IBM’s OpenPOWER Microwatt Core
IBM’s Microwatt is an open-source, RISC-based processor core designed to bring the POWER instruction set into the hands of developers, educators, and researchers. Compact and accessible, Microwatt provides a fully functional implementation of the POWER ISA, allowing for real-world experimentation and prototyping. As an open-source core, it is available on?GitHub ?for anyone to explore, modify, and use. This is an invaluable tool for learning and innovation, breaking down traditional barriers in chip design.
2. FPGA Platforms for Prototyping
Field-Programmable Gate Arrays (FPGAs) enable developers to prototype their designs on reconfigurable hardware. By loading the Microwatt core onto an FPGA, designers can bring their chip designs to life, testing functionality, debugging, and optimizing in a real hardware environment. This approach is far more cost-effective than ASIC manufacturing, making FPGAs an ideal choice for students, researchers, and startups looking to experiment with hardware.
3. OpenROAD EDA Tool: Open-Source ASIC Design
#OpenROAD (Open Runtime for Open Access Design) is an open-source Electronic Design Automation (#EDA) tool that allows for ASIC design from synthesis to place-and-route, covering the complete flow to create a ready-for-manufacture chip. OpenROAD democratizes chip design by providing a robust EDA tool that is available to everyone, addressing the need for cost-effective and accessible solutions. It also offers a unique opportunity for “Bring Your Own Code” (BYOC), letting users add custom modules or modify the Microwatt core, then synthesize and layout their design.
Together, these tools enable a flow from concept to prototype on FPGA, and eventually to an ASIC-ready design with OpenROAD.
