Hello all, does someone have an idea where to find vhdl or verilog model for 16Meg x 64 x 4 Banks DDR SDRAM? I have to simulate DDR SDRAM controller core with the memory model before I would test it with the real board which has MT4VDDT1664HG memory.

Anna, The Micron web site has simulation models for most all their components and modules. If you are not finding them, I suggest you look again.

Here is link for one chip. Look for others by yourself. http://www.micron.com/products/modules/ddrsdram/part.aspx?part=MT18VDDT3272G-26A#SIM Regards, Igor On 8/30/05, *austin at darkroom.com austin at darkroom.com>* austin at darkroom.com austin at darkroom.com>> wrote: Anna, The Micron web site has simulation models for most all their components and modules.

model for

controller core

Thank you very much indeed.

Sure I searched mircon web page well and here I am. I have IBIS files
for MT4VDDT1664HG (DDR SDRAM which I have to simulate). MT4VDDT1664HG is
a 128MB DIMM module. It' is 16 Meg x 64 x 4 banks DDR SDRAM housed on
200-pin unbuffered SODIMM package. But I have no idea how I could
simulate my controller design with Modelsim using this IBIS files (if
it's possible).
I also have (thanks to Igor) Verilog files for MT18VDDT3272G. Sure I
could use these files with Modelsim but MT18VDDT3272G is 256MB module
with 32 Meg x 72 x 4 banks housed on 184-pin registered DIMM. So it's
not exactly what I need:( or I am not right????
So what should I do?

Thanks in advance.

Best,
Anna
