摘要： The excitation of processing paths in a microelectronic circuit is organized by providing one or more pieces of input information to a decision-making software, and executing the decision-making software to decide, whether one or more of said processing paths of the microelectronic circuit are to be excited with test signals. Deciding that said processing paths are to be excited with said test signals results in proceeding to excite said one or more of said processing paths with said test signals and monitoring whether timing events occur on such one or more excited processing paths. A timing event is a change in a digital value at an input of a respective register circuit on an excited processing path, which change took place later than an allowable time limit defined by a triggering signal to said respective register circuit.
