Seven-Segment decoder as an example, the output signal of the seven were LED7S access digital pipe 7 above, high in the left, low in the right. For example, when LED7S output as Platform: |

Description: 秒表的逻辑结构比较简单，它主要由、显示译码器、分频器、十进制计数器、报警器和六进制计数器组成。在整个秒表中最关键是如何获得一个精确的100Hz计时脉冲，除此之外，整个秒表还需要一个启动信号和一个归零信号，以便能够随时启动及停止。
秒表有六个输出显示，分别为百分之一秒，十分之一秒、秒、十秒、分、十分，所以共有6个计数器与之对应，6个个计数器全为BCD码输出，这样便于同时显示译码器的连接。当计时达60分钟后，蜂鸣器鸣响10声。
-Stopwatch logical structure is relatively simple, it mainly shows decoder, prescaler, decimal counter, alarm and six counter-band components. Throughout the stopwatch the most critical is how to get an accurate pulse 100Hz time, in addition, a whole also need a stopwatch start signal and a zero signal, in order to be able to start and stop at any time. Stopwatch six output shows that were hundredth of a second, one-tenth of seconds, seconds, 10 seconds, hours, very, so a total of six counters corresponding, 6 all counter-wide code for BCD output, making it easier for At the same time show decoder connections. When the time up to 60 minutes later, the buzzer sound of ringing 10. Platform: |

Description: 七段显示译码器
因为计算机输出的是BCD码，要想在数码管上显示十进制数，就必须先把BCD码转换成 7 段字型数码管所要求的代码。我们把能够将计算机输出的BCD码换成 7 段字型代码，并使数码管显示出十进制数的电路称为“七段字型译码器”。
-Seven-segment display decoder because the computer output is BCD code, in order to display in the digital tube decimal number, it must first convert the BCD code fonts 7 segment digital pipes required by code. We can replace the computer output, 7 segment BCD code font code, and make the digital control circuit shows a decimal number called the " Seven-Segment decoder fonts." Platform: |

Description: 七段数码是纯组合电路，通常的小规模专用IC，如74或4000系列的器件只能作十进制BCD码译码，然而数字系统中的数据处理和运算都是2进制的，所以输出表达都是16进制的，为了满足16进制数的译码显示，最方便的方法就是利用译码程序在FPGA\CPLD中来实现。本实验作为7段译码器，输出信号LED7S的7位分别是g、f、e、d、c、b、a，高位在左，低位在右。例如当LED7S输出为“1101101”时，数码管的7个段g、f、e、d、c、b、a分别为1、1、0、1、1、1、0、1。接有高电平段发亮，于是数码管显示“5”。-Seven-Segment is a pure combinational circuit, usually small-scale special IC, such as 74 or 4000 Series devices only for decimal BCD decoding, digital systems, however data processing and operations are binary, so the output expression hexadecimal, in order to meet the decoding of the hex number display, the most convenient way is to use a decoding program to implement in the FPGA \ CPLD. In this study, as a 7-segment decoder, the output signal LED7S 7 g, f, e, d, c, b, a, high in the left, low on the right. For example, when LED7S output for " 1101101" digital tube 7 paragraph g, f, e, d, c, b, a, respectively 1,1,0,1,1,1,0,1. Access the high level segment shiny, so the digital display " 5" .
