• Democratizing Hardware Design

    The OpenROAD project attacks the barriers of Cost, Expertise and Uncertainty (i.e., Risk) that block the feasibility of hardware design in advanced technologies.

  • DARPA is reimagining U.S. Electronics

    OpenROAD is centered on digital SOC layout generation ("RTL-to-GDSII"), and is part of the broader DARPA IDEA program and Electronics Resurgence Initiative which seek to transform the design of hardware systems.

About OpenROAD

Problem: Hardware design requires too much effort, cost and time.

Challenge: $$$ costs and “expertise gap” block system designers’ access to advanced technology.

Objective: We want to enable no-humans, 24-hour design and catalyze open source EDA.

Foundations and Realization of Open, Accessible Design

Prof. Kahng and the OpenROAD team are aiming to develop open-source tools that achieve autonomous, 24-hour layout implementation.

OpenROAD

The Problem

Our Goal

  • 24-hour, No-Human-In-The-Loop layout design for SOC, Package and PCB with no Power-Performance-Area (PPA) loss
  • Tapeout-capable tools in source code form, with permissive licensing → seed future “Linux of EDA”

Our Approach

  • No Humans: tools must adapt and self-tune, must never get stuck unexpectedly
  • 24 hours: extreme partitioning of problems
    • parallel search on cloud
    • machine learning for predictability
  • Mantra: Correctness and safety by construction
  • Mantra: Embrace freedom from choice
  • Mantra: Often, only one thread needs to succeed

Impact

  • Create new “Base Technologies” that enable 24-hour, autonomous design
    • Extreme partitioning (bite-sized problems)
    • Parallel search and optimization
    • Machine learning: models of tools, designs
  • New paradigm for design tools and methods: autonomy first
  • Bring down barriers to democratize HW design
  • Embedded vision chips (28nm/16nm) from Michigan Internal Design Advisors team
    • Layout @Michigan: 10+ weeks, significant resource
  • OpenROAD and IDEA goal: 1 day, no humans (!)
