Re: Re: Pwr flag questionable behavior
Dick H. a écrit :
If I change the single pin name and number in the given GND_EARTH
library component from GND to EGND, then the problem goes away.
This I think is a bug.
Not a bug.
Only the pin name is used.
Invisible pins which have the Power In or Power Out electrical caract.
are automatically connected.
Because your GND_EARTH symbol has a pin named GND, this pin is
connected to the GND net.
For connection, the name of the symbol is not used (From this point of
view, if is only a comment).
A GND_EARTH symbol must be build with a single pin named GND_EARTH. (See
Eeschema doc, chapter 10.8)
In order to avoid problems, the flag "Power Symbol" must be set (In
libedit, Part Properties).
When this flag is set:
- One cannot edit the symbol name in eeschema.
- The symbol is automatically reannotated when an ERC or a netliste is made.
You can easily create power symbols with the shape you like, because it
is a component, like others components.
You cannot create a new power symbol only by editing its name: you must
create a new symbol (i.e. a new component),
with the shape you want, an a pin which have the same name as the symbol
I do not know if advantage is bigger than drawback or drawback is bigger
It is only the choice I made for eeschema
