Verilog-HDL-電梯程序

1、精品文檔這個(gè)程序不需要你再添加任何的程序，你只需要添加樓層數(shù)就可以成功控制 6 層以上電梯，另外你必須得讀懂每一塊程序的作用，才能對(duì)這個(gè)程序有更好的應(yīng)用module dtsj(clk,reset,up1,up2,up3,up4,up5,dn2,dn3,dn4,dn5,dn6,d1,d2,d3,d4,d5,d6,overw,pro,led,hex,Buzzer1,lig);input clk,reset;/reset鍵使用 keyinput overw,pro,up1,up2,up3,up4,up5,dn2,dn3,dn4,dn5,dn6,d1,d2,d3,d4,d5,d6; /故障警報(bào)鍵out
