Abstract: The method involves determining a conflict matrix per macro, selecting a macro and determining a set of macros with a connection to one of the macros, determining a sub-matrix per conflict matrix per macro in the set in relation to the interface of a relevant macro, determining a transformed conflict matrix to obtain a combined conflict matrix, determining the scan path arrangement from the relevant macro based on the combined conflict matrix. Independent claims are also included for the following: an integrated circuit with a number of macros that can be checked using a scan path in accordance with the inventive method, a computer program product for implementing the method, a data processing program for implementing the method implementing the method and a data processing system for implementing the method.
