RE: [IBIS-Users] IBIS Question

Arpad, 

 

I would tend to agree with you, as pkg parasitic should also be included for
POWER and GND pins. Couldn't this be included as a requirement in the IBIS
Spec?

Andy,

 

The problem is that the IBIS spec doesn't spell out that

the package parameters are also to be applied to power

and GND pins.  In my opinion they should be used for those

too, but it doesn't mean that all tool vendors do it.

Hi,

 

I have a question regarding the [Package] keyword in an IBIS file. As far as
I am concerned, the RLC values in this section applied to all the I/O pins,
my question is if these RLC values also applied to power and ground pins as
well? If they are not applied to power and ground pins, how can we address
the effects of different packages to the power and ground pins in an IBIS
model? (If R_pin, L_pin and C_pin for every single pin are not available,
only package min, typ and max RLC are available)

Thanks.

 

-Andy
