Design and Implementation of Universal Configurable Digital Emulators

Focusing on the universality and reusability problems of emulators in the simulation testing environment, this paper designs and implements a universal and configurable emulator for embedded systems. This emulator uses an internal logic automaton as the core, combines the generation methods of the active incentive data and the response incentive data, and simulates the internal operating logics and response handling logics of real devices. With the virtual bus, the proposed emulator can collect, deal and send the data in various application fields and network environments. Experimental results show that the emulator has a high real-time performance and operation efficiency, which can meet the requirements of the simulation and test of embedded systems.
