The HEP research project has presented an open, flexible design for a security chip. The project, “Hardening the value chain through open source, trusted EDA tools and processors (HEP),” uses open source, free components and tools to manufacture a chip at the IHP fab—the Leibniz-Institute for High Performance Microelectronics. The easy accessibility of the used process sets new standards for development times and significantly reduces the learning curve for chip design.
