Abstract: Techniques for security vulnerability assessment of security-sensitive circuit designs are described. A placement of security-sensitive components of a design may be based on constraints related to how far apart a relevant set of security-sensitive components are allowed without consuming too much power and how to optimize the placement to minimize electromagnetic side-channel leakage or other security vulnerabilities. In one embodiment, a method may receive data that includes a representation of a design of an IC and may identify security-sensitive components of the design from the data. The method may determine a placement for the design based on constraints on a level of security vulnerabilities of the security-sensitive components and may perform a power simulation for the design based on the placement. The method may generate an assessment of the level of security vulnerabilities of the security-sensitive components based on the power simulation to adjust the placement for the design.
