摘要
本文介绍了一款实用性较强的专业软件——EWB的特点,及一种由锁存器、优先编码器、同步可逆计数器和555定时器等主要元件构成的带有数码显示功能的多路抢答器的设计和仿真过程。仿真结果表明,该方案原理正确、思路清晰、实用性强。
This paper briefly introduces the character of EWB. It introduces the design and simulation of Multipath Preemption - Answer Set （MPS） which has digital - show capability. The MPS is main made of flip---latch, refusal - encoder, instep - inverse enumerator and 555 timer. The results showed that this plan is simple and feasible.
