hello

i want to knwo how to declare a DRAM, in VHDL, how to access to it and the time diagram, if it is synchronous or asynchrounous

can any one help me please

thank's
 

If you mean to say Distributed RAM by DRAM and Block RAM by BRAM in Xilinx FPGAs, then you can find it in ISE language template.
In ISE, goto Edit menu -> language template -> VHDL -> synthesis Constructs -> RAM and there you find those.

Hope this is what you meant
