SimXMD: Integrated debugging of C code and hardware components

摘要

In our demonstration, we present SimXMD, a tool that enables developers to debug microcontroller code and custom hardware simultaneously. SimXMD (Simulated eXperimental Microprocessor Debugger). SimXMD connects a GNU Debugger instance to a ModelSim instance simulating an embedded FPGA system with a Xilinx Microblaze processor. We will demonstrate debugging a multiprocessor FPGA system where the processor cores are connected through custom-designed network hardware. SimXMD is Open Source, and its modular architecture facilitates extending it to other embedded processors as well as different simulators or debuggers.
