memory

[Mandilas Antony]

i use spartan-II and verilog. i have the following problem

i want to write a dual port memory module, but i want to preload it with
some values in some specific memory locations. I have written some code
for the first part of it. but i can not do it some way to preload values
. Does anyone has any idea?

Best regards
Antony

Hi!
Xilinx Spartan II has BlockRAM support, So use their coregen utility to
generate the Dual port RAM/ROM according to your requirement.
If it is an RAM and you want to preload data, you have to have an external logic
to do so.

I think you can preload the memory locations with the value of your
choice. This facility is also available in coregen utility. But i am
not sure whether you can preload only particular memory locations with
the value of your choice. I used to work on this sort of things two
years back so may be my memory have faded a bit but anyway try it out.

Yes you can preload rams using coregen. You can specify a file that
contains the ram values to preload into memory. Or you can use the
FPGA editor to do it manually but that is a lot harder.
