We have got TriCore microcontroller and we would like to generate c code with your product, Embedded Coder in Matlab 2012b. I found a library is "Trilib" and your site I can not download it. One more question, There are some demo, or Simulink blocks for Tricore, I think driver specific blocks? And can you provide some documents about it.
It appears to me that the library you refer to was removed from the File Exchange due to licensing concerns when the File Exchange switched over to a new licensing scheme.
I suggest you examine this newer example http://www.mathworks.com/support/solutions/en/data/1-EUKQTY/?solution=1-EUKQTY
I'd suggest you look at the legacy code tool or the use of Matlab function blocks in Simulink with the %#codegen to interface to the Trilib library.
I've used all those methods to interface platform to Simulink. Each has a different advantage and/or downside.
I haven't used the Trilib myself yet, but may do the same soon enough.
