针对FPGA相关实验教学受场地和师生时间制约，并且传统的现场离线板卡实验难以统计师生教与学的过程数据，本文基于紫光同创FPGA平台，设计并实现了一套面向数字电路教学的远程实验系统。该系统融合软硬件协同设计理念，不仅实现了模拟JTAG进行远程下载与升级、代码固化、波形采集与信号发生等功能，还完成了双通道信号发生器和频谱仪的功能拓展。通过集成远程摄像头与数字孪生界面，系统可通过以太网实时回传实验现象，支持用户远程交互与实验状态监控，构建了一个沉浸式、可扩展的远程实验环境。

Aiming at the constraints of time and venue in FPGA-related experimental teaching, as well as the difficulty of collecting process data on teaching and learning in traditional offline on-site board-level experiments, this paper presents the design and implementation of a remote laboratory system for digital-circuit instruction based on the Unisoc FPGA platform. By adopting a hardware–software co-design philosophy, the system not only supports remote download/update via a emulated JTAG interface, bit-stream flashing, waveform capture and signal generation, but also extends to a dual-channel arbitrary waveform generator and spectrum analyzer. Integrating remote cameras and digital-twin technology panels, the system streams real-time experimental phenomena over Ethernet, enables remote interaction and continuous monitoring of experiment status, and thus establishes an immersive and scalable remote laboratory environment.
