Okay, thanks. I’ll familiarize myself with that effort. However, this is
The new interconnect BIRD will allow you to define blocking caps in either
the on-die interconnect, or package interconnect.
If you’re talking about tool-specific pseudo-comment style augmentation, I’d
I assume that there are other EDA tools besides ours that allow the user
to define package and on-die subckts that are either s-parameter or SPICE
(IBIS-ISS) subckts that contain blocking caps.
I don’t think so; at least, not completely. But, I do appreciate the reply! :)
Does this answer your question?
Walter

Thanks, Bob!
What is, currently, the preferred way of representing a d.c. blocking
capacitor in the signal path of a Rx model, assuming I'm okay with a
lumped element representation?
Thanks,

Hi David,a
Yes, Terminator is illegal. According to the [Algorithmic Model]/[End
Algorithmic Model] Usage Rules (Section 10.1):
Usage Rules: The [Algorithmic Model] keyword must be positioned within
[Model] section and it may appear only once for each [Model] keyword
in a .ibs file. It is not permitted under the [Submodel] keyword or
in [Model]s which are of Model_type Terminator, Series or Series_switch.

Hi all,
Is Terminator still an illegal model type for AMI Rx models?
Thanks,
