本程序实现了一个信号发生器。此信号发生器是由两个完全相同的可自加载加法计数器LCNT8组成，它的输出信号的高低电平脉宽可分别由两组8位预置数进行控制。

本程序实现了一个信号发生器。此信号发生器是由两个完全相同的可自加载加法计数器LCNT8组成，它的输出信号的高低电平脉宽可分别由两组8位预置数进行控制。-This procedure implements a signal generator. This signal generator is made up of two identical adder can be loaded from the counter LCNT8 compo

这个是用VHDL实现的正负脉宽调制器，同样是对新手有帮助，高手不必看了。-This is achieved using VHDL positive and negative pulse width modulator, the same is to help novice, you do not have to read. Ha ha

vhdl交通灯控制电路实现，和LCNT8实现，程序为单进程，可读性好，技巧性高。-vhdl traffic light control circuit and LCNT8 achieve the program as a single process, readability skill.
