本文实现了8通道的12位D/A模拟输出板卡的设计。该设计是基于FPGA的3U CPCI板卡，可以提供8通道的模拟电压和电流输出，各路电压输出范围可以配置成0~5V、0~10V、-5~5V或-10V~10V，各路输出电流可以配置成4~20mA、0~20mA或0~24mA。本设计摒弃了常规的CPCI接口芯片，采用FPGA十PCI IP CORE的设计方案，大幅度提高了系统的集成度和调试速度，缩短了系统的开发周期。方案使用专门的WDM (windows driver model)开发工具Driver Studio，成功实现了内核模式驱动开发的设计目标。-This realization of the 8-channel 12-bit D/A analog output board design. The design is FPGA-based 3U CPCI board, provides 8 channels of analog voltage and current output, and the brightest output voltage range can be configured as 0 ~ 5V, 0 ~ 10V,-5 ~ 5V or-10V ~ 10V, the brightest output current can be configured as 4 ~ 20mA, 0 ~ 20mA or 0 ~ 24mA. The design abandoned the conventional CPCI interface chip, an FPGA ten PCI IP CORE design, greatly improving system integration and debugging speed, shorten system development cycle. Program using a special WDM (windows driver model) development tool Driver Studio, successfully developed a kernel-mode driver design goals.
