Hansel,
I recommend you use the Pulse Response jargon.

Hi Walter,
I thank you for the prompt reply.
Yes, that is correct the number is the same but the jargon that needs to go
into the specification may require us to mention either a pulse or step
response.
I too have been scratching my head over the last week and hence thought it
would be best to enable a discussion if a BIRD is to be drafted.
Thanks,
Hansel Dsilva

Hansel,
I think the number reported is the same whether doing a Pulse response or a
Step response analysis.

Hi,
Subject, "Gap in IBIS for sampling with statistical mode AMI models",
presentation at the DesignCon 2020 IBIS Summit.
We are working on a BIRD in enabling when in the AMI_Init flow for an RX
IBIS-AMI model to tell the EDA tool the cursor sampling point time (seconds).
In IBISv7.0, the AMI_Init flow calls out an impulse response which involves a
stimulus of 1/time step and does not have any information on the unit interval
(UI).
The question to ourselves is whether it would it be preferable to make the RX
IBIS-AMI model when in the AMI_Init flow to output the cursor sampling point
with regards to a pulse response or step response?
Below is a overview on impulse, pulse and step response in enabling a
discussion. Feel free to correct me if I happen to be going in the wrong
direction.
