This paper details the results of the Xilinx-Ansoft collaboration and will provide an overview of the 10Gbps design kit that enables Xilinx customers to rapidly evaluate their board designs. Readers will learn how to use the design kit for electromagnetic field simulation coupled with circuit and system simulation to predict performance of their circuit board designs. Details on the methods for generating frequency- and time-domain results such as high-frequency insertion loss, TDR impedance plots, eye diagrams, and channel-to-channel crosstalk are given. The full channel simulations result in the insertion and return loss profiles as a function of frequency. Readers will learn how to set parameters for output voltage swing, pre-emphasis, and equalization within the FPGA to overcome the predicted channel distortions.
