Building IBIS-AMI Models from Datasheet Specifications
Some high-speed SerDes devices do not come with IBIS-AMI models. For situations when an AMI model is not available, this paper describes a process for building IBIS-AMI models using SerDes datasheet information and lab measurements. The process is illustrated using a case study of a PCIe Gen3 8 Gbps SerDes device by fine-tuning SiSoft Advanced Technology models to capture important behaviors. Stress tests and eye scans are used to further tune and correlate the model to actual hardware. This paper was nominated for Best Paper Award at DesignCon 2016 for its practical approach to a problem faced by every SI Engineer.
