Defines a templated primitive.template <Type1 arg1, ..., TypeN argN = DefaultN> ... { Contents; } THDL++ allows defining templated entities, classes and functions. See the related pages for more details.

THDL++ are similar to VHDL generics. However, unlike VHDL generics that are limited to numbers, any THDL++ primitive can be specified as a template argument. E.g. an entity, class, template, or a list. Use the any keyword when specifying type for such "extended" template arguments.
