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

频率计VHDL编程。设计一个4位数字显示的十进制频率计，其测量范围为1MHz，测量值通过4个数码管显示以8421BCD码形式输出，可通过开关实现量程控制，量程分10kHz、100kHz、1MHz三档(最大读数分别为9.999kHz、99.99kHz、999.9kHz)； 当输入信号的频率大于相应量程时，有溢出显示。 -Cymometer VHDL programming. Design of a 4-digit decimal display frequency, the measurement range of 1MHz, the measured value through the four LED 8421BCD code shows the form of output can be controlled through the switch range, range at 10kHz, 100kHz, 1MHz Three (maximum reading were 9.999kHz, 99.99kHz, 999.9kHz) when the input signal is greater than the corresponding frequency range, it shows overflow.
