Abstract

This paper focus on the testability analysis of co-designed data-flow specifications. The co-designed specification level implies a high level testability analysis, independent of the implementation choices. With respect to testability, the difficulties of generating test sets, detecting and diagnosing faults are discussed and estimates are proposed. A hardware modelling, based on information transfers and called the Information Transfer Graph, is adapted to the specifications. A real case study supplied by Aerospatiale illustrates all the evaluations.
