Apparatus (100) for monitoring timing of a plurality of critical paths of a functional circuit (101), the apparatus (100) comprising: a plurality of canary circuits (103_1 to 103_n), each coupled to a critical path of a functional circuit (101) for detecting and outputting critical timing events, each canary circuit (103_1 to 103_n) comprises an adjustable delay element (307_1 to 307_4); an analyser circuit (105) for receiving a count of the critical timing event output from at least one of the plurality of canary circuits (103_1 to 103_n) for a predetermined time interval for a plurality of delay values of the adjustable delay elements (307_1 to 307_4) and determining a probability distribution of critical timing events of the at least one of the plurality of critical paths for the predetermined time interval for the plurality of delay values. |
