High speed digital (HSD) serial-deserializer (SerDes) system channel simulation is critical for SerDes system design and validation. The simulation must run fast while achieving adequate accuracy. Today’s SerDes system vendors require HSD IBIS-AMI (Input/Output Buffer Information – Algorithmic Modeling Interface) models long before silicon is available. To meet the demand, HSD silicon vendors desire an effective process for generating IBIS-AMI models efficiently and reliably.
This paper was presented at DesignCon 2015 and proposes a new methodology for AMI model development. Included are discussion of the challenges facing the IBIS-AMI model development, engineering trade-offs needed, modeling methodology and an application on a Xilinx developed HSD IC. The methodology was proven to have shortened the Xilinx development cycle over the previously used method for a 20nm 32Gbps SerDes IC. The developed IBIS-AMI model is tested across multiple EDA platforms. Detailed modeling techniques for accuracy and speed improvement are discussed throughout the paper.
