数字密码锁具体要求如下：
1. 系统密码设置使用拨位开关sw[7:0]，限定为4位密码；sw[7:6]、sw[5:4]、sw[3:2]、sw[1:0]分别对应从左到右密码的第1、2、3、4位；每一位的取值范围限定在0、1、2三个数中。
2. 用btn[2:0]作为输入键，btn[0]、btn[1]、btn[2]分别对应的有效输入为十进制数0、1、2（由于btn数有限，系统不支持解锁含有数字3的密码）。
3. 输入的密码显示在7段数码显示管对应位上，顺序为从左至右，未输入密码时数码管不显示数字，只有对应位输入密码后数码管才点亮。
4. 输入密码与预存密码相同时，开锁成功，LED灯ld[7]亮起；否则开锁失败，ld[0]亮起。
5. 具有一个复位按键btn[3]。按键后，回到初始状态。
