Abstract
The present disclosure includes systems and methods relating to information flow tracking and detection of unintentional design flaws of digital devices and microprocessor systems. In general, in one implementation, a technique includes: receiving a hardware design specifying an implementation for information flow in a hardware configuration; receiving one or more labels annotating the hardware design; receiving one or more security properties specifying a restriction relating to the one or more labels for implementing an information flow model; generating the information flow model; performing verification using the information flow model, wherein verification comprises verifying whether the information flow model passes or fails against the one of more security properties; and upon verifying that the information flow model passes, determining that an unintentional design flaw is not identified in the hardware design.
