Please send me an example too if any body is familiar with accessing bram content.

hi.i am doing project aes algorithm using bram.can any one help me
 

accessing a BRM is really fundamental. Provide an address and get a dword.

Was there anything a bit more specific?
 

since i am new to programming of bram using core generation .how to write program in verilog
 

You might want to take a look at the pdf documents for bram. Generate a bram memory core with coregen from ISE, and then do *clicky* on the "Datasheet" button. That has plenty of info including some code snippets. That's assuming it was xilinx bram, but hey totally valid random guess on my part what with your lack of detail. :p
 

i have read pdf files of core generator.the examples given in that are done with inference .i want examples using core generator
 

I'm not quite sure I follow. Do you want someone to outline all your work for you? Or ...
