i tried three or four types one by giving whole [7:0] to one bram location doesn't work either.and also 4 bits to one and 4 bits to others.
The thing i want to know is how to enter values on these bram location. i have 8 bit data bus.ramb16 means one location has to be 2kb.and i have 32 locations.so how this 2kb per location will work.guide me out.i have seen xilinx data2mem pdf file but no help in this matter.
waiting for responce.
