设计的随机数发生器可产生两个随机数，由一开关（RIN）进行控制，RIN为1时随机数发生器被清除，RIN为0时随机数发生器将产生1-6的两个随机数，可由LED数码管显示，显示的方式可由设计者自行设计，既可以选择数码管中的任两个LED显示随机数，也可让四位LED同时显示一个随机数（按一定的时间跳转显示）。根据给定的材料完成上述系统的设计，用Xilinx ise完成功能的设计与仿真，并最终下载到目标板XILINX SPARTAN-3 Starter Board上进行验证实现。-The random number generator can be designed by a random, produce two control switch (RIN), RIN is 1 random number generator is cleared, RIN is 0 random number generator will produce 1-6 two random, but by LED digital display, showing the way tube by designer to design, can choose the digital tube as two LED display random, also can let four leds also showed a random number (according to certain time jump displayed). According to the given material to complete the above system design, complete with the functional design of ise Xilinx with simulation, and finally downloaded to target Board SPARTAN- 3 Starter Xilinx Board test the realization.
