Zuken has a simulation design kit for Virtex-5 FPGAs from Xilinx.

The kit is to be used with Zuken's CR-5000 Lightning design platform, providing a set of topology templates, in-context HTML documentation and useful content for simulation of waveforms and eye patterns.

This simulation kit is provided free of charge to CR-5000 Lightning users via their LinkZ login.

The templates are ready to use and help users to save time in designing and analysing printed circuit boards by eliminating many common manual tasks. Because much of the pre-design work is already done, the templates within the simulation kit allow a user to plan and constrain a design more efficiently, even adhering to common pre-defined sets of standards.
