In 1978, Carver Mead, a professor at the California Institute of Technology, and Lynn Conway at Xerox PARC invented a computer-aided design method for integrated circuits. They used a set of design rules to describe chip scaling so that engineers could easily design very-large-scale integration (VLSI) circuits without much knowledge of process technology.
That same sort of capability is needed for 3D chip design. Today, designers need to know chip design, system-architecture design, and hardware and software optimization. Manufacturers need to know chip technology, 3D IC technology, and advanced packaging technology. As we did in 1978, we again need a common language to describe these technologies in a way that electronic design tools understand. Such a hardware description language gives designers a free hand to work on a 3D IC system design, regardless of the underlying technology. It’s on the way: An open-source standard, called 3Dblox, has already been embraced by most of today’s technology companies and electronic design automation (EDA) companies.
