The tight interaction among an ever increasing amount of software functions and hardware subsystems (mechanics, hydraulics, electronics, etc.) leads to a new kind of complexity that is difficult to manage during mechatronic design. System tests have to consider huge amounts of relevant test cases. Validation with limited resources (time and costs) is a challenge for the development teams. A new instrument is presented that should help engineers in dealing with the complexify of test and validation. TestWeaver is based on a novel approach that aims at maximizing test coverage with minimal work load for the test engineer for specifying test cases. The method integrates simulation (MiL/SiL) with automatic test generation and evaluation, and has found successful applications in the automotive industry. The approach is illustrated using a 6-speed automatic transmission for passenger cars. Also presented is the way TestWeaver and Modelica simulators can work together.
