我是VHDL的初学者，这是我自己编译的简单的几个VHDL码，功能有3-8解码器及其testbench,16位寄存器及其testbench和交通灯。 希望能和其他初学者一起讨论学习，并得到高手的指点-I VHDL beginners, this is my own translation of a few simple VHDL code. 3-8 function decoder and testbench, 16 Register and testbench and traffic lights. Hopes to be able to discuss other beginners learning, and with the guidance of the master
