I'm looking for a VHDL example code to implement a DDR memory in a Altera 'Stratix'. (not a controler), with use of RAS, CAS, etc... There is many example of memory in Megawizard of Quartus (DP-RAM, FIFO), but I can't find DDR.
I would like to have this DDR include in specific memory block (M-RAM or M512 or others).
Thanks for your help,
