Rules for Schematic Symbols

There is an unspoken “rule” in the industry which states power pins need to be placed at the top edge and ground pins at the bottom edge. This is an archaic rule.

As the adage goes, the only thing that is constant is change. I could not agree more. Therefore, to succeed we must be able to adapt to changes. This can apply to schematic design. I believe we need to reconsider (and perhaps change) some of the rules for schematic symbols most of us have been following for approximately the last 40 years. By doing so, we will start to create a more readable and effective schematic layout.
