Abstract:
This invention relates to fault detection in electrical circuits, in particular it relates to fault detection for a plurality of adjacent input circuits. The invention provides a method and apparatus for detecting a control or communication fault on an analogue circuit by simulating said analogue circuit using a simulated circuit comprising digital circuit components; the simulated circuit receiving a control input to provide a first output; and the analogue circuit receiving said control input to provide a second output; and setting an error condition when the first output and the second output differ.
