分频选择系统。inclk0端输入25MHz信号，通过altpll倍频为400MHz信号C0端输出，需求不一样自己改倍频器参数。分频器clkdiv用来二分频、四分频、八分频、十六分频，分别分频为200MHz、100MHz、50MHz、25MHz四种频率信号输入到选择器中。选择器的TCLK是外部输入信号，A[3..0]是四个独立按键，选择器是用按键的不同组合来从四个分频喜好和一个TCLK中选择一路输出。代码清晰易懂，不符合需求请自行扩展-Frequency selection system. the inclk0 side input 25MHz signal, multiplier by altpll at 400MHz signal C0-ended output, demand not the same as their own to change the parameters of frequency multiplier. The divider clkdiv used divided by two, divide-eighth of the frequency, and 16 divided by, respectively, are at a frequency of 200MHz, 100MHz, 50MHz, 25MHz four kinds of frequency signals input to the selector. Select the TCLK is an external input signal, A [3 .. 0] four separate buttons, selector all the way to the output with a different combination of buttons to choose from the four sub-frequency preferences and TCLK. Code is clear and easy to understand, does not meet the needs of your own expansion
