Tool/software:
Hi,
I've been working with the provided IBIS-AMI model for this device in Hyperlynx for the past few weeks and have noticed some issues with the model:
- I had to (with the help of a Siemens rep) make modifications to the .ami file in order for the repeater functionality to work. This is because the model is quite old and supports repeaters using a standard that was proposed to the IBIS council at the time but ultimately not adopted in favor of a different standard. This problem cost me a *lot* of time in troubleshooting
- Performance: Simulations using the model take 3 to 4 order of magnitude more time than identical simulations using different repeater models. This makes sweeping parameters and optimization go from a 2 day job to a 2 week job, with most of it spent waiting for sweeps to run.
- Occasional erratic results: In some configurations the model would radically misbehave and return results that are clearly physically impossible or unreasonable, with no common thread between offending configurations.
It is clear to me that this model is old and needs a touchup, at bare minimum for compliance with the actual IBIS standard.
