这是一个用vhdl语言实现dds的例子，已在quartusII里调通并可以下载到实验箱上，功能正确-This is a use of VHDL language dds example, has been in tune quartusII pass and can be downloaded to the experimental box, the function correctly

vhdl语言，交通控制信号，指示车灯的变化情况，仿真顺利通过可以使用-vhdl language, traffic control signal, indicative of changes in the lights, the simulation can be used successfully passed

简易的VHDL程序，主要实现ALU的逻辑功能，进行选择和数据的移动。很适合初学者对VHDL的理解。内含有testbench可以进行Qutarus的仿真-Simple VHDL program, the main achievement of the ALU logic functions, to select and move data. VHDL is suitable for beginners to understand. Containing a simulation testbench

vhdl learning materials，-VHDL based on the digital clock has an alarm clock, stopwatch, clock, date, stopwatch functions can start, pause, cleared, the clock can be set-up times, you can set the date
