IBIS-AMI and SerDes FAQs
What is IBIS-AMI?
The IBIS Algorithmic Modeling Interface (IBIS-AMI) is a modeling standard for SerDes PHYs that enables fast, accurate, statistically significant simulation of multi-gigabit serial links.
What are the main goals of SerDes Modeling?
- Interoperability: Different vendor models work together
- Portability: One model runs in multiple simulators
- Flexibility: Support for Statistical and Time-Domain simulation
- High Performance: Simulate a million bits per CPU minute
- Accuracy: High correlation to simulations / measurement
- Security: represent IP behavior without exposing internal details
What are the benefits of IBIS-AMI?
IBIS-AMI models make multi-million bit simulations practical, accurately model vendor-specific equalization and clock recovery algorithms and make mixed-vendor analysis quick and easy. IBIS-AMI allows commercial channel simulators to provide the same levels of performance and accuracy as proprietary semiconductor vendor tools.
What is SerDes Equalization?
SerDes (Serializer-Deserializer) Equalization enables data rates we would not have thought possible, and it continues to be the secret sauce of serial links. While good performance depends on doing basic things in hardware, it is arguably the configuration of SerDes Equalization Settings that determines eye margins.
Why should I optimize the analog channel and SerDes IP?
Optimization is important because you can reduce system costs without sacrificing reliability.
