Abstract

Continuously shrinking feature sizes lead to an increasing vulnerability of digital circuits. Transient faults may tamper the functionality. Design automation is required to analyze whether faults may induce erroneous output of a circuit. In this paper, the design tool RobuCheck is presented to analyze the influence of transient faults on a circuit's behavior. As a result, the tool identifies components that require protection to obtain fault tolerance. Furthermore, an overall robustness estimation of the circuit is determined.
