SV-XC : DPI Interoperability Requirements

The respective areas for DPI Interoperability are:
    I. SystemVerilog Interoperability with SystemC Using DPI
   II. SystemVerilog Interoperability with HDL PLI's (VPI/VHPI)
  III. DPI Interoperability with C++
  IV.Other requirements on DPI Interoperability
 
Questionnaire
=============
I.SystemVerilog Interoperability with SystemC Using DPI
 
 1. Do you have requirements for  invoking DPI functions/tasks from 
    SystemC? 
 
     If the answer is yes, please provide inputs for the following 
     questions:
 
  A. Do you require invoking SystemC functions as DPI  import 
     functions/tasks? What is the typical functionality that you want 
     to achieve in these functions.
 
  B. From within the SystemC portions of the design do you require 
     calling SystemVerilog DPI export functions?
 
  C. Do you require calling SystemVerilog export tasks consuming time 
     from SystemC threads.
 
II. SystemVerilog Interoperability with HDL PLI's (VPI/VHPI)
 
 1. Do you foresee a requirement for calling DPI export functions from 
    Verilog-VPI or VHDL-VHPI callbacks? 
 
     If the answer is yes, please provide inputs for the following 
     questions:
 
  A. What is the nature of functionality you expect to achieve through 
     such calls?
 
  B. What are the callbacks from which you want to make a call to DPI 
     export functions? Are these object callbacks, or simulation phase 
     callbacks (which ones)?
 
 
III. DPI Interoperability with C++
 
  1. Interoperability for DPI import functions/tasks
 
   A. Does the current use model of allowing execution of  DPI import 
      functions defined as C functions in C++ suffice your requirements?

      Namely, a C function will have to be enclosed inside
            
             extern 'C' {
              }
   
   B. Any other requirements you have on DPI Import tasks/functions?
 
  2. Interoperability for DPI export functions/tasks
 
    A. Is there a requirement to declare a static method of an 
       SV class as an export function?
 
IV. Other Requirements on DPI Interoperability
 
     Please do provide inputs on any aspects that you consider important

     for DPI interoperability which have not been covered above.
