【应用手册】AN543: Debugging Nios II Software Using the Lauterbach Debugger This application note presents methods of debugging a Nios® II application with the Lauterbach TRACE32 Logic Development System. The TRACE32 system, including Lauterbach PowerTrace hardware and the TRACE32 PowerView integrated development environment (IDE), provides complete visibility into the operation of a Nios II system. In combination with the Nios II EDS, SOPC Builder, and the Quartus® II software, the TRACE32 system enables you to analyze Nios II system failures or anomalous design behavior. The Lauterbach TRACE32 system gives you a degree of control unmatched by other Nios II debugging environments. This application note includes tutorial steps for debugging an example design on the Altera® Cyclone® III 3C120 development board, and general guidelines for debugging a custom design. This application note assumes that you are running the Lauterbach TRACE32 PowerView IDE on a Windows platform. However, the techniques presented are independent of the platform.
