Hi, I am using Coregen (update 3) from within ISE (7.1 update 4). I added a new source from IP, and defined a RAM. This opens the Coregen window, where I can customizet the RAM. I defined the width and depth and added a .coe file for the initial values.
I am sure the format of .coe if perfect, since I can see the coefficients using the button "See coefficients".
However, when I use this RAM in my design (.xco), and try to read the contents, it doesn't seem like they're actually present. At first, I kept reading don't cares and now, somehow, it shows zero initial values.
I use the ISE simulator and I checked the signals down to the memory. Its the memory output which is 0, whereas I was expecting the initial values.
Is the initial value information included only during synthesis or is it used during simulation as well??
Thanks in advance,
Robert.
