Abstract:
1. A method for locating circuit deviations between a circuit and a reference circuit, wherein the circuit and the reference circuit are describable by signal-flow graphs comprising a plurality of function blocks, wherein the function blocks are coupled in the signal-flow graphs by connecting an output of a function block which is upstream in the signal flow to an input of a function block which is downstream in the signal flow, and wherein a circuit input is respectively coupled to an input of one of the function blocks, and a circuit output is respectively coupled to an output of one of the function blocks, the method comprising the steps of: assigning function blocks of the circuit to corresponding function blocks of the reference circuit, and identifying those function blocks of the circuit for which it has not been possible to assign any function block of the reference circuit, and which have disposed upstream in the signal flow at least one function block to which it has been possible to assign a function block of the reference circuit.
