Hi All,

As mentioned during the meeting I have attached a simple 2 way DPI example.

If you look at tb.sv you will see that in line 53 a simple C function is
called. The only thing you need to do to make this work is to "import" the
function which is done in line 20.

Then in the my_function.c code the C function calls a SV function which is
defined in the tb.sv file. To call a SV from C you need to "export" the
function which is done in line 25 of the tb.sv code.

A simple struct (packet) is passed from SV to C and back to SV again.

Would this be possible with the VHPI?

Regards,
Hans.
