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.
