Take its complement by applying DeMorgan’s theorem to obtain F in the form of product of complemented products.

VHDL的寄存器读写参考，可自己根据要求重新修改，本示范只做参考用-Register read and write VHDL reference to their request to amend in accordance with, the reference model only

硬件描述语言VHDL的频率计程序,可用于做实验,或者初学者借鉴.-Hardware Description Language VHDL of the frequency counter program can be used for experiments, or the beginners learn.

该程序用来实现电话计时以算取费用，比较简单(telephone cost metering verilog code)

Verilog HDL编写的键盘扫描程序，考虑了判断按键弹起的问题。程序按一定的频率用低电平循环扫描行线，同时检测列线的状态，一旦判断有一列为低则表示有键被按下，停止扫描并保持当前行线的状态，再读取列线的状态从而得到当前按键的键码；等待按键弹起：检测到各列线都变成高点平后，重新开始扫描过程，等待下一次按键。-Written in Verilog HDL keyboard scanner, taking into account to determine key bounce problem. Program according to a certain frequency of scan lines with low-level circulation lines, while testing out the state line, once the judge has said there is a classified as low-key is pressed, stop the scan and to maintain the current line-line state, and then read out line state to get the current keys key codes to wait for key pop-up: To detect the lines at all out into a high level after the re-start the scanning process, waiting for the next key.
