[SI-LIST] Re: IBIS for DDR2 DIMM

Dear Supratim,

Based on DDR simulations I have carried out using XTK, it is very =
helpful
(necessary) to obtain the board  (i.e. .brd) file of the DIMM together =
with
stackup information and DIMM's bill of material.

The nets which need to be simulated can then be examined for routing and
component types.

The models for passive components (such as capacitors or termination
resistors) can be readily constructed from knowledge of package type and
component values.  The models for the ICs (such as DDR SDRAMs, =
Registers,
PLLs,) can be obtained in IBIS format.

Knowing the board routing (plus stackup geometry) and the components on =
each
net, allows extraction/creation of topology, model and other files as
required for (hierarchical) DDR simulations.

Subject: [SI-LIST] IBIS for DDR2 DIMM


Hi All,

I want to do SI for my ASIC interface to DDR2 DIMM Module (micron).I =
down=20
loaded the IBIS for DIMM but I am looking different IBIS not for DIMM. I
have confusion in collecting IBIS models for it. The problem is I am not =

sure do I need to collect IBIS for DIMM module alone or for all =
components=20
of DIMM module.
Any suggestions appreciated.

Regards,
Supratim
