If a supply pin (with pin direction Sup) is placed on a net (with ADD,
MOVE) then this net segment will receive the name of the supply pin.
If the last supply pin on a net is deleted, it is given a new, automatically
generatedname.
CheckandCorrectSchematic
A schematic diagram must be checked with the aid of the Electrical Rule
Check (ERC), when the design of the schematic diagram has been com
-
pleted, if not before. The ERC writes all its warnings and error messages
intoatextfile(*.erc),anddisplaysthisfileinathetexteditorwindow.
Please check all the messages and make corrections in the schematic, if
necessary.RunERCagaintocheckyourefforts.
Pleaseremember:
The ERC checks the schematic diagram according to a rigid set of rules.
It can sometimes happen that an error message generated from your
schematiccanbetolerated.
Ifnecessary,makeanoutputofthenetand pinlists(EXPORT).
SHOWallowsnetstobetracedintheschematicdiagram.
Experience has shown that printing out the schematic diagram by means
ofthePRINTcommandishelpfulwhensearchingforfaults.
In the case of a corresponding board file, the ERC also checks the con
-
sistency between schematic and board. If there are no differences, ERC
reports Board and schematic are consistent at the end of the text file.
Otherwise the message Board and schematic are not consistent will be
prompted.ThedifferenceswillbelistedintheERCfileabove.

SuperimposedPins
Pins will be connected if the connection point of an unconnected pin is
placed onto the connection point of another pin. Pins will not be con
-
nected if you place a pin that is already connected to a net line onto an

otherpin.
