The 7 series GTX transceiver is the first 28 nm transceiver in the FPGA industry and supports line rates from 500 Mb/s to 12.5 Gb/s. To enable fast high-speed serial link simulation and accurate link margin estimation, Xilinx provides an IBIS-AMI model kit for the 7 series GTX transceiver. The features and the quality of this IBIS-AMI model kit are the subject of this white paper.
