Sample Set Selection in Fault Injection Based on Multisignal Modeling Methodology

摘要

To find scientific sample set for fault injection, the multi-signal model is used to describe the circuit board. The formalization definition and modeling step of multisignal methodology are introduced. The relationship between sample set and fault injection cost, accuracy, damage, repeatability is analyzed. A fault sample set selection method based on multi-signal modeling methodology is presented. It makes a compromise between fault number and injection cost, accuracy, damage, repeatability, etc. The adequacy verification of coverage for the sample set of fault injection is discussed. Finally, an example proves that the method can achieve nearly optimal verification effect, which can achieve higher efficiency.
