Development of Intelligent Digital Circuit Test Module Based on VXI Bus

摘要：

In this paper, an intelligent digital circuit test module based on VXI bus is developed using universal bus simulation technology. Composition and design principle of the hardware and the software are given in the paper. To reduce the area of the circuit board, the logic circuit of the hardware is realized using CPLD devices, the design of which makes the delay time between two test sequences be zero. The module can be operated by the softpanel directly or programmed by calling the given drive functions. Experiment shows that the module can well accomplish simulation test function for microprocessor -based and other bus-structured intelligent digital circuit boards.
