Undirectional verification of bus-based systems

摘要

Disclosed is a testing unit (210; 300) for testing a data transfer and/or an addressing scheme in a bus-based system. The testing unit (210; 300) comprises a data generator (250) for generating an expected data pattern, and a comparator (260) for comparing the expected data pattern with a data pattern received from a sending unit (200; 300) within the system. The data generator (250) is adapted to generate the expected data pattern in a defined relationship with the data generation of the data pattern received from the sending unit (200; 300). Preferably, the defined relationship is an algorithmic relationship and might be based on the address of the testing unit (210; 300).
