This thesis presents a novel approach to operation-centric tracing for hardware debug with a retrospective analysis of traces which are distributed across a computer system. Therefore, these traces record entries about the operations at runtime, and a software tool correlates these entries after a problem occurred. This tool is based on a generic method using identifiers saved from operations. Because identifiers are changed along the path of an operation through the system and traces record different information, the entries are transformed to find matching entries in other traces. After the correlation, the method reconstructs the operation paths with help of an operation graph which describes for each type of operation the subtasks and their sequence. With these paths the designer gets a better overview about the chip or system activity, and can isolate the problem cause faster. The TRACE MATCHER implements the described method and it is evaluated with an example bridge chip. Therefore, the benefit for hardware debug, correctness of the reconstructed paths, the performance of their Implementation, and the configuration effort are evaluated. At the end guidelines for trace and system design describe how matching can be improved by carefully designed identifiers at operations.
