WP1: “Design for Test”


Cost of specification-based tests


  • For complex systems, it has been demonstrated that it is generally cheaper to verify the physical integrity of the device rather than its functional behaviour.
  • Our research aims to develop structural-based testing by providing the necessary knowledge to the community:
    • Fault modelling and fault simulation: models generally cover the nominal first order behaviour of MNT devices. Links between levels of abstraction (FEM, nodal, VHDL-AMS) are not common.
    • Defects and failure modes: Defects in MNT are strongly dependent on both technology and application.
