Power and Gnd Pins in IBIS

[mars_dong]

Hi All,
Does anybody know how the software treat the Power and Gnd Pins in one IBIS model? and how the software distinguish Power pins with different potentials?
Thanks in advance!

 

[jay_ec_engg]

first tell me what is IBIS model ??

Dear Mars_dong,
I suggest IBIS can not deal with Gnd bounce! The other similsr issue is propegation delay!

 

[Johnson]

for jay_ec_engg:
IBIS which stands for I/O Buffer Information System is a I/O block modeling tool.

You can find quite a lot of information about IBIS (I/O Buffer Information Specification) and ICM (IBIS Interconnect Modeling Specification) at the websites of the IBIS Open Forum, the industry group which manages both standards:

Please note that SSO and other power delivery issues can be simulated using IBIS, but that the exact implementation is tool-dependent. There are several discussions of this in the Summit presentations under the "Upcoming Events" link above.

I hope this helps!

Which tools can simualation Pwr and Gnd by IBIS model?

 

[mmirmak]

It would be improper of me to recommend specific tools. However, you can see several different presentations on power/ground and SSO modeling from EDA tool vendors in the IBIS Summit presentation index, **broken link removed**.

Also, most tool vendors who support IBIS in their tools are listed on the IBIS Roster page, **broken link removed**. You can consult their company descriptions and examine their own websites to see which ones best fit your needs.
