Hello Vinod,
I have no experience with lauterbach, however for the cmm files, you can download the source code from NXP software website (you need the access to the Automotive SW - S32G2 Standard Software).
In the Automotive SW - S32G2 Standard Software select the EVB DIAGONOSTIC TESTS

Then download the SW32G2-EVBDIAG-EAR-0.8.4, the cmm files is in the directory Tools\Scripts\cmm\Customer
