Design and Implementation of Analog Channel Control Circuit Based on CPCI Bus

This paper focuses on design and implementation of a digital control circuit based on CPCI (Compact PCI) bus, and gives the schematic and PCB (printed circuit board) design and the design of logic control of local bus data transmission. It uses PCI9054 as the bridge chip and FPGA (Field Programmable Gate Array) chip as a timing control chip. Utilizing integrated development tools and hardware description language to realize the development of the logic and driver. This circuit design has passed the practical application and its performance is excellent to detect the external device's working modes and word state.
