General Order of nine methods for hardware and software debugging

Objective:

1, this article mainly from the book "Debugging Nine Law: Hardware and software errors of the way" author David J.agans, belongs to reading notes + personal experience.
2, the purpose of this book is not to prevent, protect and screen to prevent the emergence of bugs, but how to find bugs and repair them, how to efficiently track and solve difficult to detect hardware and software problems, not specific platforms, languages or tools, do not involve the obscure test theory.
3, after you look, may be a sound, said, "I have always done so!" "Well, congratulations, you're an engineer who can solve problems efficiently.

The book mentions nine rules, can be said to summarize the system and comprehensive, according to these steps and requirements to do, to solve the problems encountered in the work and bugs, have a great help!

• Understanding the System
• Manufacturing failure
• Do not think, but to see
• Divide
• Change only one place at a time
• Maintain Audit trails
• Check the plug
• Get a new perspective
• If you don't fix a bug, it will always exist
