RE: [sv-bc] question from sv-cc on the funtion_prototype

I have to take back what I said earlier. The implicit default return type for a function is a 1-bit reg.

However, I still think it is useful for a prototype to require an explicit return type.

Françoise,

It might have helped to provide a link to the original SV-CC issue http://www.eda.org/svdb/bug_view_page.php?bug_id=0000049

I think the question is "Can section 27.4.5 be modified to explicitly require that all functions specify a return data type, there is no implicit return type?"

I believe the answer is yes, all functions (and full prototypes) require an explicit return type.

Perhaps I am missing something, but I don't see how SystemVerilog could do anything with the return value of the imported DPI function if it didn't know what type of value was being returned.
