The title “analog debugging” seems a bit enigmatic. After reading it, an embedded firmware developer may suffer from cognitive dissonance; but trust me, it will make sense later. What the title ...

Make it a habit to dig deeper and find more information about the issue before starting to debug a non-trivial issue. For example: is this a new problem? If so, starting when? Is this only visible to ...

Key Takeaways Reproducing errors consistently makes analyzing and fixing issues easier and more structured.Tools like debuggers, logs, and performance monitors ...

Design verification has been the biggest challenge for any IC design company for decades now. EDA tools and verification methods have evolved a lot over the last two decades, but along with that, the ...

As many kernel developers and hackers have known for years, loadable/unloadable kernel modules (like user-space applications) are almost never bug-free. With the continuing use and development of ...

There appears to be an unwritten law about the time spent in debug-it is a constant. It could be that all gains made by improvements in tools and methodologies are offset by increases in complexity, ...

Adding assertions early and throughout the ASIC design cycle is the best way to independently check that design code reflects the intended behavior as specified in design specifications and the ...

Testing is an integral and important part of any software development cycle, open or closed, and Linux kernel is no exception to that. Developer testing, integration testing, regression, and stress ...

Debug consumes more time than any other aspect of the chip design and verification process, and it adds uncertainty and risk to semiconductor development because there are always lingering questions ...

Scan is a structured test approach in which the overall function of an integrated circuit (IC) is broken into smaller structures and tested individually. Every state element (D flip-flop or latch) is ...
