Virtex-5 White Papers

This white paper updates the results from the 2005 Xilinx Rosetta experiments published in IEEE Transactions on Device and Materials Reliability, clarifies some open issues, and presents additional results for 90 nm and 65 nm technology nodes.

This white paper describes a rarely noticed design technique that can make a difference in the size and the performance of your FPGA design. Control signals on FPGA flip-flops have a built-in priority. If you can learn to write code that is sympathetic to the priorities, the results will be rewarding. This white paper provides some simple VHDL and Verilog examples to explain key points.

This white paper gives an overall view of the various mainstream digital television standards and outlines related Forward Error Correction solutions available from Xilinx for cable, satellite, terrestrial, and mobile systems.
