Help me with address for loading data in the BRAM

[LatDrIvE]

Hello All,
there is a 32bit Data Bram. I am trying to load a 32 bits data in the fourth location (4) of the Bram (0-255 locations).

The addresses are :
Address Map for Processor ppc405_0
(0b0000010000-0b0000010011) ppc405_0
(0b0000100000-0b0000100011) ppc405_0
(0x40000000-0x40007fff) docm_cntlr docm
(0x80000000-0x8000ffff) LEDs_16Bit plb
(0xffff8000-0xffffffff) iocm_cntlr iocm

In order to load the 32 bit data in the fourth location of the Dataside Bram the given address for this location from my testbench will be the

address<= "0000000000000000000000000000100" (location 4)
or should be given as
address <= "1000000000000000000000000000100" [(0x40000004]?

The question is how i will load 32 bits data in a specific location of memory (BRAM Xilinx) according to the address map above from a VHDL testbench?

Re: Data-side BRAM

Use the BRAM wizard tool that comes with the ISE toolset. It will allow you to set up your BRAM with data already loaded in a specific location.
