Abstract: An experimental design method based on NI myDAQ pocket platform and Multisim Simulation is proposed to solve the problems of analog electronic circuit experiment limited by classroom and traditional instrument. Firstly, students receive the design task requirements through Rain Class, and they use Multisim for project design, parameter estimation, circuit simulation and test. After that, the circuit hardware is built on the bread board, then the circuit is debugged and the fault is analyzed by using NI myDAQ pocket platform. Finally, the simulation results are compared with the hardware circuit parameters to be further adjusted to achieve the optimal circuit design. The results show that the combination of virtual and real teaching mode can effectively improve students' comprehensive circuit design ability and independent innovation ability.
