Circuit and Method for Protecting Asynchronous Circuits
Résumé
The present disclosure relates to a fault detection circuit comprising: sampling elements (SE_1 to SE_L) configured to sample signals present at a plurality of nodes (n1 to nL) of an asynchronous circuit (100); a logic circuit (110) configured to determine a number of tokens (Ν' ) in the asynchronous circuit based on the sampled signals; and a comparator (112) configured to compare the determined number of tokens with a reference value (N), a fault being detected based on said comparison.
