| Abstract: | This paper briefly introduces the character of EWB.EWB is developed by Interactive Image Technologies,which is aimed to solve the problems encountered in electronic design.It introduces the design and simulation of Multi-route Priority-answer Set(MPS) which has digital-show capability.The MPS is main made of flip-latch,Refusal-encoder,Instep-inverse enumerator and 555 timer.This paper persents a method of system modeling and simulation based on EWB platform.Finally,the circuit is tested in the environment of EWB,which indicates the scheme is feasible. |
