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.
See also page 78 for further information concerning Forward&Back
Annotation.
PointstoNotefortheSchematicEditor
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.
OpenPinswhenMOVEing
If an element is moved then its open pins will be connected to any nets
or other pins which may be present at its new location. Use UNDO if
thishashappenedunintentionally.
MergeDifferent Schematics
The commands GROUP, CUT, and PASTE can be used to copy a sche
-
matic or parts of it into another one. To do this open a schematic, dis
-
play all layers (DISPLAY ALL), select all objects that should be copied
with GROUP, and select the group with CUT and a right mouse click.
OpenanotherschematicnowandusethePASTEcommand.
While inserting a group EAGLE checks the objects' names and com
-
pares them with those already existing in the schematic. If there are
matchestheaffectedobjectstobeinsertedgetnewunequivocalnames.
This works also with board files, provided there is no consistent schematic
available.
