how to read address in RAM

Hi,
In Leon3's testbench, I am putting some C program in PROM (i.e. replacing PROM.srec with my C program lets say add.srec).
The code of C prog is follows
---------------------------------------------------
#include <stdio.h>

#include <stdlib.h>

int main(void)

{

int a=2,b=3,c;

c=a+b;

printf("Sum=%d",c);

printf("c address =%p",&c);

return 0;
------------------------------------------------------
After compilation in BCC(TSIM) i am getting correct output.
Means c's value 5 and address for c is something 0x4000af60.
Now I am compiling this C program in testbench with the help of ModelSim.
I want to see the same address or value of C in ModelSim also.
Please tell me how to do this?

Please also tell how to validate the result in BCC and ModelSim?

You can not expect the address of variables to be the same for different environments and compilers. If you depend on the address value, your C code is non-portable, and that should be avoided in general, not just in this case. It is OK to depend on the value of the variable c.

Then how i can read the value or address in the modelsim?

You can let the C code store the value of the variable to a fixed address:

*((int *) 0x1234) = c;

Replace 0x1234 with the address you want.
