请教为什么不能仿真电路图
下面这个原理图是简单的8路抢答器怎么仿真不了?不论按哪个键(S1-S8)LED数码管显示不正确。请高手帮我看看。http://cache.amobbs.com/bbs_upload782111/files_23/ourdev_515859.JPG

why are you so eager to contradict yourself? 不论按S1-S8任何一个键LED1正确会点亮,U2(数码管)的显示不出1-8的数字。是不是线路有误? "不论按S1-S8任何一个键LED1正确会点亮,U2(数码管)的显示不出1-8的数字。"
what does that tell you?
if you can simulate the circuit and if your circuit does what you want it to do are two totally different questions.
