Democratizing Chip Design with IBM’s OpenPOWER Microwatt Core, FPGA Platforms, and OpenROAD EDA

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.

Why Democratizing Chip Design Matters

In an era where digital devices are everywhere, the ability to design custom chips could redefine industries, especially for organizations with specific hardware needs. Democratizing chip design holds promise for:

  • Education: Students and educators can get hands-on experience, preparing the next generation of engineers with skills that were once only accessible in high-budget labs.
  • Innovation: Startups and individual creators can develop hardware tailored to unique applications without needing millions in capital.
  • Research: Researchers can explore and validate new architectures without depending on proprietary hardware.

Open-source chip design provides more control, flexibility, and transparency, encouraging innovation at every level.

How to Get Started with Open-Source Chip Design

  1. Explore the Microwatt Repository: Check out IBM’s Microwatt on?GitHub?to understand its structure, capabilities, and potential modifications.
  2. Learn FPGA Basics: Many online resources and tutorials are available for FPGA programming. Start with programming basics and work your way up to loading complex cores like Microwatt.
  3. Install OpenROAD: Download OpenROAD and get comfortable with its workflow by following its documentation, learning about each design stage, from synthesis to routing.
  4. Experiment with BYOC: Begin with small modifications to Microwatt—such as adding a custom ALU function or memory interface—and use OpenROAD to observe the impact on synthesis and layout.


Conclusion

The combination of IBM’s Microwatt core, FPGA platforms, and OpenROAD EDA tools has brought about a powerful shift in hardware design. By making these tools accessible to everyone, we can encourage a new wave of creativity and innovation, enabling people to prototype, test, and potentially manufacture custom chips. The democratization of chip design has far-reaching implications—not just for individual learners but for the tech industry, enabling personalized hardware solutions and giving creators unprecedented control over their designs.

As more people and organizations join this open-source movement, the future of chip design will become more collaborative, dynamic, and accessible. So why wait? Get started today and be part of this hardware revolution.

Waiting for more open source CMOS PDK’s e.g. 90nm … 65nm to implement ‘payable’ systems …
