An I2C verification environment, which uses memories and VPI (c code) to drive and monitor data to/from DUT, will be described in this work.

1. In this site many verification environments have been presented, using, specman , VHDL etc....
   The main page of this work is accessed with the following link.
   This page describes how APB transaction are done.


2. The test-bench is build of a few blocks. The verilog test-bench contains a BFM and requests item from a c code generator. The bench also collects data and send them to the c code. The c code passes it on to a scoreboard, which is implemented in c++.


3. In this page I show my first steps in calling a function from c to c++.
   To check the concept, I created small c++ function, a header file and main in c, which calls the c++ function.


4. The c++ code is listed below:
   
   #include
   extern "C" int print(int i, double d)
   {
     std::cout << "i = " << i << ", d = " << d << " \n";
   }
   
   


5. The header is also simple:
   
   extern "C" int print(int i, double d);
   


6. The main is written in c:
   
   #include "l.h"
   
   int main() {
     int i;
     double d;
   
     i=2;
     d=5.0;
   
     print(i, d);
   }
   


7. Use the following commands to compile and run:
   
   g++ f.cpp m.c
   ./a.out
   


8. My next step in this self study project was to implement a simple scoreboard
   in c++.
