@mariuslucianand:
The file it is trying to read has an error in the path it is looking in, I'm using an S32K144, and the path is pointing to:
Matlab Add-Ons\Toolboxes\NXP_MBDToolbox_S32K1xx\mbdtbx_s32k\devices\S32K116\signal_description\S32K144\.mat
Bold added for clarity, there is an obvious error in that path looking for S32K144 related files in the S32K116 branch of the directory tree.
Clarifying information provided in the original report, using the png I attached as reference to produce that path.
