Hi faweiz,
Officially, the S12ZVMx Toolbox v1.3 was validated/tested on the following Matlab releases:
- R2013A, R2013B, R2014A, R2014B, R2015A and R2015B
- 32-bit and 64-bit
Since the toolbox was released on November 27, 2015 - those were the only Matlab options at that time.
Nonetheless, the toolbox can be also installed on the 2017a and can be used for code generation.
The only option that "might" not work is the Processor-in-the-loop simulation due to changes in the Matlab environment.
In regards with the main question: "S12ZVM toolbox cannot be found in Simulink toolbox library" i presume it is a simple to fix Matlab glitch.
Please have a look at this: https://community.nxp.com/message/915480?commentID=915480%23comment-915480#comment-911873
Also, keep in mind that you:
1: need to successfully install a Toolbox license prior of seeing in it in the Simulink library;
2: need to execute the mcd_s12z_path.m script from toolbox root directory to setup the environment;
Hope this helps!
Daniel
