DPI layer

Anyone knows whether class can be passed over DPI layer? has anyone
written anytype of wrapper between SV and C++ code?
Thank You.

It is not clear to me if you are referring to a
SystemVerilog class being passed as a formal argument
to an imported C function or a C++ class being passed
to an exported SystemVerilog task or function.

In any case, under SV3.1A, you are not permitted to do
either with a class as a formal argument.

You may find the following tutorial on DPI SV layer

Thanks for the response.
I am referring to a SV class being passed as a formal argument to an
imported C++ function.

Now that you brought it up,I can see how useful it is to go from C++ to
SV by passing the class to an exported SV task.
