Patent ID: 7003422

Claim:
A method for simulating and testing a circuit unit to be verified, in which method interface data streams of the circuit unit to be verified are exchanged with test bench elements in a test/simulation device, having the steps: (a) connecting a circuit unit to be verified to at least one test bench element shell of a test/simulation device in order to transfer and switch interface data streams which are correspondingly output to associated test bench elements by the circuit unit to be verified; (b) connecting the at least one test bench element shell to the test bench elements in order to transfer test data streams which are output by the test elements to the circuit unit to be verified; (c) controlling the at least one test bench element shell by means of a shell control data stream which is provided by a test bench controller; (d) evaluating the interface data streams by a test bench element shell which is connected to the test bench elements, in order to check the correct operational capability of the circuit unit to be verified; and (e) configuring interfaces of a circuit unit to be verified by means of signal values at specific connection elements of the circuit unit to be verified and the corresponding shell, a predefinable signal value at a connection element of the circuit unit to be verified defining, during a reset phase, whether an interface is operated in an X mode or Y mode.
