  Bouchra,

  Yes, there is. It can be accomplished with IBIS EBD (Electrical Board Description). The EBD parameters are described in the IBIS 3.x versions of the IBIS specification.

  Writing them manually, however, for something on the scale that you are looking for would be very demanding both in terms of the volume of text and being able to accurately describe the transmission line paths. The best way to create an EBD for an extensive case would be to have your SI tools export/write it. Also, you should assess carefully exactly what you want to achieve and determine if an EBD is the right thing to do and be aware of the limitations in EBD descriptions. For example, transmission line interconnects described in EBDs do not include coupling. When such effects are important, you will be better to use the multi-board functionality in your SI tools. EBDs are, perhaps, best used only for the actual board-to-board interconnects rather than the on-board interconnects.

  Regards,
  Tony

    I would like to ask you if there is any way of creating an IBIS model for a whole board (here memory board). Where to find such info? Is it easier to do it from the design or actual model? what are the tools?

    Thanks in advance
    Bouchra
