2、容，可將設(shè)計(jì)將分為五個(gè)模塊來(lái)設(shè)計(jì)：分頻計(jì)數(shù)模塊、時(shí)間模塊、加分模塊、動(dòng)態(tài)掃描顯示模塊、LED燈模塊。2、整體設(shè)計(jì)流程： （1）、分頻計(jì)數(shù)模塊：通過(guò)分頻模塊，將試驗(yàn)箱自帶的50MHZ的頻率分頻得到1MZ以及1HZ的頻率 （2）、時(shí)間模塊：將計(jì)時(shí)器的分鐘、秒鐘，通過(guò)借位的方式設(shè)計(jì)成40分鐘的倒計(jì)時(shí)時(shí)鐘 （3）、加分模塊：通過(guò)撥盤開關(guān)的選擇，輸入A、B隊(duì)的比賽得分 （4）、動(dòng)態(tài)掃面顯示模塊：通過(guò)1MHZ的頻率，將時(shí)間以及A、B隊(duì)的比賽得分同時(shí)掃描顯示在數(shù)碼管上 （5）、LED燈模塊：對(duì)上下場(chǎng)的顯示，以及比賽結(jié)束的燈亮延長(zhǎng)顯示四、設(shè)計(jì)說(shuō)明1、 設(shè)計(jì)程序library ieee;use ieee.std
