可编程逻辑  FPGA设计重利用方法(Design Reuse Methodology)

&nbsp; FPGAs have changed dramatically since Xilinx first introduced them just 15 years ago. In thepast, FPGA were primarily used for prototyping and lower volume applications; custom ASICswere used for high volume, cost sensitive designs. FPGAs had also been too expensive and tooslow for many a ...
