Electrical fault insertion testing with ADvantageFC.

An advanced solution for interactive and automated electrical fault insertion, ADvantageFC combines a scalable fault matrix with the ADvantage Framework to verify and validate system response to induced faults; sensor failure, signal short etc.


  • This High Level application provides an intuitive environment for all to use;
    • Intuitive command structure – short (signal) XYZ to ground

ADI Fault Insertion Systems have a common architecture built around the fault relay matrix


Insert a fault matrix between the real-time simulation and the device under test. The fault matrix comprises fault buses where each I/O line to the DUT has one relay on each fault bus in the system. The fault buses are paired providing SIADvantageFC_FaultMatrixM and DUT buses separated with an isolation relay. A Real Kit relay on the SIM side allows the insertion of real sensors or equipment into the system. The fault matrix is scalable, 1 – 4 fault bus pairs. With more fault bus pairs a greater variety/quantity of faults can be inserted at any one time.




The fault matrix is managed through the ADvantageFC Application.  The fault matrix is annotated with real signal names for ease of use and fault management.ADvantageFC_GUI_Graphic_Upper


  • Open and close relays manually; ad-hoc fault evaluations, hardware debugging
  • Build up the fault using real signal names and predefined fault commands
  • Automate the fault evaluation – create and manage reusable fault libraries
  • Deterministically manage faults using a dedicated logical device in your Simulation project
  • Monitor and track current state of the fault matrix
