RE: [IBIS-Users] IBIS Question

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
