减1计数器 一、设计要求 用Verilog HDL语言设计一个计数器。 要求计数器具有异步置位/复位功能，可以进行自增和自减计数，其计数周期为2^N（N为二进制位数）。 二、设计原理 输入/输出说明： d：异步置数数据输入； q：当前计数器数据输出； clock：时钟脉冲； count_en：计数器计数使能控制（1：计数/0：停止计数）； updown：计数器进行自加/自减运算控制（1：自加/0：自减）； load_d-a counter a reduction, design requirements using Verilog HDL design of a counter. Asynchronous requests with counter-home/reset functions can be carried out by self and self-count reduction, cycle counting of 2 ^ N (N for binary digit). Second, the principle of design input/output Description : d : asynchronous home several data input; Q : The current counter data output; Clock : clock pulse; Count_en : Counting enable control (1 : Counting/0 : Stop counting); Updown : dollars several self-Canada/reduction Operational control (1 : Since the plus/0 : Since decrease); load_d

说明：  该资料是用vhdl编写的按键消抖程序，按键消抖在使用按键的数字电路中非常重要，如果不对按键信号进行处理，有可能会出现大量错误的按键信号。文件key_xd.vhd是按键消抖程序，文件key_xd.vwf是仿真波形文件。该程序已经通过仿真测试，并且在电路板上调试通过，效果理想。(The information is written in the key consumer vhdl shaking procedures, key consumer shaking in digital circuits using the buttons is very important, if not key signal processing, there may be a lot of the wrong button signal. File key_xd.vhd is key consumer shake procedure is the simulation waveform file key_xd.vwf file. The program has been tested by simulation and debugging in circuit board by, the results are satisfactory.)
