How do I make use of local-clocks in a Virtex-2 FPGA?

Hi, there: I saw this statement in Virtex-2 datasheet, how do I make use of these local clocks? Is there any documents on these local clocks?

Best Regards, Kelvin

Local Clocking In addition to global clocks, there are local clock resources in the Virtex-II devices. There are more than 72 local clocks in the Virtex-II family. These resources can be used for many different applications, including but not limited to memory interfaces. For example, even using only the left and right I/O banks, Virtex-II FPGAs can support up to 50 local clocks for DDR SDRAM. These interfaces can operate beyond 200 MHz on Virtex-II devices.
