Abstract: Online debugging is indispensable in design and development of FPGA, but the traditional debugging methods cannot meet the growing needs of FPGA. Online debugging software based on soft core is designed, which realizes signal acquisition in the chip by soft core and graphically displays the debugging information, then describes the methods and steps of online debugging software for FPGA debugging with actual use case. The results show that, it has good user experience, debugging efficiency and debugging accuracy, and plays a positive role in promoting the domestic FPGA industry.
