Abstract

A method of monitoring a processing circuit is disclosed. The processing circuit is operable, in a normal operation mode, to generate a sequence of trigger commands, with at least one trigger command of the sequence of trigger commands including time information. At least one window sequence with a closed window period and an open window period is generated such that the duration of the closed window period and/or the open window period is defined, at least in part, by the time information. It is detected if one trigger command is received within the open window period of the at least one sequence.
