Mandilas Anton #1 / 4	memory 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

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. Rajkumar...

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. pranav

Jo #4 / 4	memory 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.
