The design process is a creative process and intuition is the most important skill you rely on first. Once you have a design, then you apply your analysis skills to evaluate the cost-performance tradeoffs.
That's a statement taken from a blog by Eric Bogatin, a signal integrity expert.
In his latest entry Bogatin says that he likes "to think of intuition as what you take away after you have done the reasoning what has become ingrained in your understanding and you trust to use every day. It becomes your 'common sense' of the right way of doing things."
Bogatin claims that "the better your intuition or common sense about signal integrity, the better your first pass design will be. This translates to a shorter and lower cost design process.
"Because signal integrity is sometimes 'anti-intuitive', we sometimes have to 're-calibrate' our intuition for these analog electromagnetic effects important in interconnects."
Bogatin teaches a "The Essential Principles" class about building a strong foundation for a common sense about signal integrity.
I think we need more philosophers like Bogatin to explain the essentials of electronics to us. Read his blog entry here.
It might reset what you thought you knew about signal integrity.
