While most embedded software issues can be debugged using specific code such as print statements or a JTAG-based debugger/emulator, there are many cases where the embedded software engineer can benefit from a logic analyzer. This paper explores the qualities of logic analyzer for real-time embedded software troubleshooting.
We've always found logic analyzers to be a great debugging aid - a single byte written to an I/O port (to be logged via the logic analyzer) has significantly lower time/space overheads than a printf. Plus the timestamping element of the logic analyzer is great for supporting timing analysis.
