Re: Any Good Reason to Create a Hierarchical Connector and Conductors to Route (Plumb) Ground Out of a Hierarchical Schematic
|
Hello eetech00:
?
Break a huge schematic that has grown so large it can't be easily read from one monitor into a dozen sub-schematics.
Those sub-schematics now have grounds peppered all around.
This lead me to the question which is the title of this thread.
?
I did not intend to add grounds.
I wanted to understand the ramifications of leaving those to-be-hidden grounds behind, or routing ground out of the hierarchical schematic to be connected on a top level schematic.
?
After these discussions, I understand the need to remove all triangular (label 0) ground symbols from the interior of a hierarchical block and physically connect any nets that may have been disconnected by those ground symbol removals.
?
I discovered first hand those confusing probe readings within a sub-circuit as detailed in my have a look here submission.
?
All for now
?

HI eewiz ?
I see what you've explained.
But in my humble opinion, it appears to be caused by a misuse of labels. When you add a ground symbol, you are basically adding a reserved label named "0" (zero). It has been known for years that a net should not have multiple dis-similar labels.
What is the intent of internally grounding the RTN pin?
