I have the following UCF file for Spartan-6 FPGA. Currently I am using Virtex-5 XC5VLX20T ff323 to implement my design. How can I convert the same file according to Virtex 5. If someone has already, please share.
A Spartan-6 is a different family, different package, different pinout part. There is no "magic" conversion between the devices. You pick new pins on the Virtex-5 that have the same functionality as the ones that were used on the Spartan-6. e.g. put the clk pin on a dedicated MRCC (multi-region clock capable) pin, use the pin that has a reset cicruit on the board for rst, etc.
