Software updates at regular intervals ensure that diagnostic testers are assigned all the latest functions. The ECUs required for a regression test must be available in entirety and in all variants to be able to ensure sufficient test coverage. As this is usually impossible, a simulation is the required solution. With the simulation, it is easy to select ECUs and ECU variants: All you have to do is exchange simulation files in the unit. You can take care of this manually using the intuitively operable graphic user interface or conveniently in test automation with the DLL interface.
The ECU simulation TestCUBE2 is the counterpart for all cases of application in which an ECU is not yet (e.g. preparation of workshop tests) or no longer (e.g. tester regression test) available.
