The following table summarizes the code generation keys that will be recognized in the template file. type can be any of BOOL, INT and REAL. Keys are case sensitive and are always in capital letters. Most of the keys can be used with both the C/C++/Java generator and the VHDL, while a few keys are unique for one of the generators. The table specifies with an X for which code generators the key can be used.
