Heya everyone..
I have stored the image in BRAM by .coe file now, i just want to read the stored data from BRAM and display it on PC using VERTEX ML403,
i have verilog code where i am reading the image from stored bram.
You'll need some form of communcation - probably easiest would be an RS232 serial core. They are quite simple and there are plenty of examples out on the internet.

Why are you both trying to infer a memory (the always blocks in posts #1 & #3) and instantiate a memory. You have two drivers on the output douta (i.e. one from the always block and one from the instance bram.
I also don't get you second code I've never seen a memory in an FPGA that allows for no write enable? Your code in post 1 with the exception of the both an attempt to infer memory and instantiate the same memory aside is closer to being usable than the code in post #3.
You need to read a Verilog book and go online and read some of the Verilog tutorials. I don't think you know anything about instantiating a module and what that really means. (FYI, it's like sticking ICs on a breadboard and soldering wires to connect them to other ICs).
