US Patent 11663382 Systems and methods for hardware trojan detection and mitigation

Disclosed herein is application specific integrated circuit (ASIC) redesign for security and analysis testing tool, which includes hardware description language code with on-chip security circuitry for detecting and mitigating hardware Trojan horses (HTHs) in an ASIC chip. The testing tool is used between a design stage of the ASIC chip and a synthesis phase of production of the ASIC chip to add test circuitry to the ASIC chip in order to facilitate testing and protecting of the ASIC chip from the HTHs long after production. The test circuitry facilitates search for HTHs, HTH triggering events, and changes made to the ASIC if the HTH has been activated.
