：ISE5.1i是Xilinx推出的具有ASIC-strength的设计工具，它充分发掘了VirtexⅡPro系列芯片的潜力；Virtex-II Pro 系列芯片的密度是从40,000门到8,000,000门。同4.1i相比，设计人员在编译时所花的时间得到了成倍提高（从100,000/min增加到200,000门/min）并且在器件速度上增加了40 。-: ISE5.1i is a Xilinx introduced a ASIC-strength design tools, which ful

Modern serial data protocols (e.g., FireWire, SONET, ATM, T4) sometimes require clocks that are faster than maximum FPGA global clock speeds. To solve this problem, the incoming clock (200 MHz in the example below) can be used to demultiple
