Embodiments of systems and methods for an FIB-aware anti-probing physical design flow are described in the present disclosure. Such embodiments incorporate new and improved security-critical steps in a physical design flow, in which the design is constrained to provide coverage on asset nets through an internal shield.

Prevention of front-side probing attacks

A method of assessing vulnerability of Integrated Circuit (IC) can include: preparing a list of logic nets of the IC; obtaining rectangular segments from the logic nets; finding a milling exclusion area based on a covering wire; and superimposing the found milling exclusion area onto the rectangular segments of the logic nets. The milling exclusion area is an area that microprobing attack does not succeed without cutting off at least one of the rectangular segments.
