UK defence contractor BAE Systems is using a security digital twin of a RISC-V processor from SiFive for a radiation hardened chip for space applications.
Cycuity in the US has developed the digital twin technology for security assurance for third-party intellectual property (IP). One of the concerns about using third-party IP is that it can introduce potential system-level security vulnerabilities due to its high configurability and programmability. Verifying the highest levels of assurance for third-party IP components is important to safeguarding microelectronic systems.
The three-way collaboration developed a scalable framework based on Common Weakness Enumeration (CWE). Cycuity’s Radix tool creates a security digital twin of an IP block which can then be re-verified by a system-on-chip (SoC) integrator at the block and full chip levels to provide assurance of the third-party IP.
