说明： EDA实验--RAM实验:利用-MegaWizard Plug-In Manager创建一个16×8的RAM，通过编程对RAM进行读写并在显示器上显示。
本例使用三个按键PSW3，PSW2，PSW1，分别对应顶层文件中的x，y，we，we＝1对RAM写，xy＝11时，写入10101011；当xy＝01时，写入01010101；当xy＝10时，写入10101010。we＝0时，对RAM读出。三个按键按下时为0，当PSW1健按下时对RAM进行读出。
(EDA Experimental RAM experiment: the use-MegaWizard Plug-In Manager to create a 16 × 8 of the RAM, through the programming of the RAM read and write and displayed on the monitor. This example uses three buttons PSW3, PSW2, PSW1, corresponding to top-level document x, y, we, we = 1 on RAM write, xy = 11, the write 10101011 when xy = 01 hours, write 01010101 when xy = 10, the write 10101010. we = 0 when read out of RAM. Press the three keys for 0, when PSW1 Kin-pressed to read out of RAM.)
