// See t_dpi_accessors.v for details of the test. This file should be included
// by the top level module to define all the accessors needed.

   // Use the macros to provide the desire access to our data. First simple
   // access to the registers, array elements and wires. For consistency with
   // simulators, we do not attempt to write wires.

    // we do not attempt to write wire slices.
