Request the DDR2 SI simulation Methodology

[xunzhaoziwo]

Hi, Bros
I want to do some SI simulations to the DDR2 memory with SO-DIMM slot.
I do not know the target Memory Stick information, I mean it end user would probably use any memory stick. And I do not have the SPICE, RLGC or S-parameters of the SO-DIMM connector.
But I know the IBIS model of memory controller.
Then who can help me on the Methodology of DDR2 SI simulation?
what software I should use, and what is the solution to this kind of simulation?


Thanks for your kindly help!

James

hi

thats how i did:
1.) i have chosen a type from the micron semiconductors, because they have simulation models for their memories
2.) download the fullboard hyperlinx model of the memory module board. download the ibis modells of the memory chipc used on the module.
3.) use hyperlynx for multiboard simulation.
4.) on the memory board, assign chip ibis models for those locations/numbers what will be used in an usual module.
5.) simulate chip-to chip! the signals can seem to be useless on the connector-pins, but dont worry: those have to be good at the chips i/o pins. (check for standard DDR2-eye)
6.) you will tell to your customers, that the board is validated in simulation with the xxx type from micron, but probably it will work with other types/brands too. and its their responsibility to use another type.
