Hi, Nimish, As far as I know, the newer Simulink versions are (still) backwards compatible with the .mdl file format. The .slx file format is NOT backwards compatible with earlier versions of Simulink. The xps_library and casper_library block libraries are therefore still in the .mdl file format so as to be compatible with as wide a range of Simulink versions as possible.
Are you sure that the new Simulink requires that you save the model files in .slx format or do they just recommend that you do that? If you've upgraded your mlib_devel version, you might want to try running "update_casper_blocks(bdroot)" with your block diagram opened. That will (try to) replace the CASPER blocks in your model with new copies of the blocks from the newer mlib_devel. Unfortunately, I have not been able to make this script work for all possibilities so you might not be able to use it, but it's certainly worth a try as it updates everything automatically for you. If you try it and encounter problems, please let me know (preferably via the list).
