Method and system for transforming recorded communication data

A method for transforming recorded communication data via a first program, the communication data being provided by messages from a network or bus communication, the recorded communication being carried out on a basis of a first communication matrix, the recorded communication data being provided to be sent via a test system to an ECU under test, the test system being connected via a first communication link to the ECU under test that is configured based on a second communication matrix, the method comprising:

• a) reading the first and second communication matrix;
• b) comparing elements of the communication matrices by:
• i) assigning identical or corresponding elements;
• and
• ii) categorizing changes in the elements of the second communication matrix as compared to the elements of the first communication matrix;
• c) determining the data to be transformed, wherein the data to be transformed are given by those communication data that are adapted to be assigned to an element of the first communication matrix that corresponds to an element of the second communication matrix, wherein the element of the second communication matrix has categorized changes as compared to the corresponding element of the first communication matrix;
• d) processing the communication data by:
• i) transforming the determined data according to predefined rules to the categorized changes;
• ii) discarding the recorded communication data, which can be assigned to an element of the first communication matrix for which no identical or corresponding element exists in the second communication matrix;
• e) sending the recorded data that is not to be discarded or transformed and sending the transformed data to the ECU under test or saving the data to be sent in a file.
