    Hi all,
    Hi all,
    i got a problem in building 32X32 LUT ROM from 32X1 ROM which is there
    in unisim library
    i am not able to figure the thing how we have to use 32 "init" values
    when using for generate
    the 32X32 ROM using 32X1 ROM
    can anyone help me in understanding the usage of INIT for the ROM
    and after that

    i tried that but i am getting new problem in using 32 INIT statemetns
    as i am using
    "for generate" loop to instantiate 32X1 ROM 32 times, but i am using
    only one INIT attribute and passing all 32 values to that INIT in
    generic map
    but as i am using only INIT it is giving me an error when i tried to do
    synthesis for the same 32X32 ROM
    can anyone tell me how to use 32 32 bit values to instantiate 32X32 ROM
