设计并调试好一个能产生”梁祝”曲子的音乐发生器，并用EDA实验开发系统（拟采用的实验芯片的型号可选Altera的MAX7000系列的 EPM7128 CPLD ，FLEX10K系列的EPF10K10LC84-3 FPGA， ACEX1K系列的 EP1K30 FPGA，Xinlinx 的XC9500系列的XC95108 CPLD，Lattice的ispLSI1000系列的1032E CPLD）进行硬件验证。

设计思路

根据系统提供的时钟源引入一个12MHZ时钟的基准频率，对其进行各种分频系数的分频，产生符合某一音乐的频率，然后再引入4HZ的时钟为音乐的节拍控制，最后通过扬声器放出来。

-Design and debug a good one can produce　The Butterfly Lovers　piece of music generator, and the development of EDA experimental system (to be used in models of experimental chip with optional Altera s MAX7000 series EPM7128 CPLD, FLEX10K series EPF10K10LC84-3 FPGA, ACEX1K Series The EP1K30 FPGA, Xinlinx the XC9500 series XC95108 CPLD, Lattice s ispLSI1000 series 1032E CPLD) for hardware verification. Design according to the system clock source provided by the introduction of a benchmark 12Mhz clock frequency and its various sub-sub-band frequency coefficients, resulting in consistent with the frequency of a particular music, and then the introduction of 4Hz clock control for the music beats, and finally through Loudspeakers released.
