RT-level fast fault simulator

In this paper a new fast fault simulation technique is presented for calculation of fault propagation through HLPs (High Level Primitives). ROTDDs (Reduced Ordered Ternary Decision Diagrams) are used to describe HLP modules. The technique is implemented in the HTDD RTlevel fault simulator. The simulator is evaluated with some ITC99 benchmarks. A hypothesis is proved that a test set coverage of physical failures can be anticipated with high accuracy when RTL fault model takes into account optimization strategies that are used in CAE system applied.
