Design of VXI Universal Bus Emulator

Simulation test is commonly used for fault test of microprocessor circuits. In this paper, universal bus emulation technology is used to design a VXI universal bus emulator to make the fault test system test diversified microprocessor circuits. The test results show that the emulator can meet various requirement for the microprocessor circuits test. Therefore, the universal bus emulator can be used to establish automatic test system of microprocessor circuits.
