Abstract: The invention provides a method for connecting test bench elements (102a–102f), and a shell device, a test bench element shell (201) partially or completely surrounding a circuit unit (101) to be verified, so that test bench elements (102a–102f) can be connected to the test bench element shell (201). Test data streams (203a–203f) pass in each case between the test bench elements (102a–102f) and the test bench element shell (201), the test bench element shell (201) which surrounds the circuit unit (101) to be verified being connected via interface data streams (P0(0)–P0(7), P1(0)–P1(7), 204a, 204b, 204c) to the circuit unit (101) to be verified. The test bench element shell (201) ensures that in each case a specific protocol with associated operations can be executed, during which process, depending on the configuration, an interface exchanges interface data streams (P0(0)–P0(7), P1(0)–P1(7), 204a–204c) of the circuit unit (101) to be verified with the corresponding test bench element (102a–102f).

Abstract: A fault search method and apparatus for simplified use and control of fault search in a system with several different models such as, for example, a hardware model, a software program and a test bench model. A user activates a uniform debugger, which, in turn, retrieves and executes various subordinate debuggers that are each allocated to a different model. The subordinate debuggers then access the different models allocated to them for the performance of corresponding fault search operations.
