Avionics Wiring Fault Detection IP

FPGA cyber security

Wiring Fault Detection (WFD) for military and commercial avionic data buses.

Based on the Sital patented passive TDR technology, the WFD is an FPGA IP.
The WFD IP augments the standard standard bus communication with real-time information concerning the physical condition of the network.


  • Extend real-time wiring diagnostics information from your interface card or avionic system
  • Avoid aircraft grounding due to faulty communication lines
  • Shorten repair time by pinpointing the exact location of the wiring fault
  • Eliminate “No-Trouble-Found” scenarios for intermittent wiring disconnects during flight


  • Manned/Unmanned Aircrafts
  • Manned/Unmanned Military vehicles
  • Smart buildings
  • Mining Equipment
  • Cargo Ships and Tankers

The WFD is available for evaluation and licensing. Please contact us to obtain more information
