Consistency Check
This command is used to test schematics for electrical errors. The
summary is written into a text file with the extension .ERC.
The following warning messages may be generated:
- SUPPLY Pin Pin_Name overwritten with Net_Name
- NC Pin Elem._Name Pin_Name connected to Net_Name
- POWER Pin El._Name Pin_N. connected to Net_Name
- only one Pin on net Net_Name
- no Pins on net Net_Name
- SHEET Sheet_Nr.: unconnected Pin: Element_N. Pin_N.
The following error messages may be generated:
- no SUPPLY for POWER Pin Element_Name Pin_Name
- no SUPPLY for implicit POWER Pin El._Name Pin_Name
- unconnected INPUT Pin: Element_Name Pin_Name
- only INPUT Pins on net Net_Name
- OUTPUT and OC Pins mixed on net Net_Name
- n OUTPUT Pins on net Net_Name
- OUTPUT and SUPPLY Pins mixed on net OUTNET
Additional messages may be produced by the automatic
Consistency Check.
Consistency Check
The ERC command also performs a
Consistency Check
between a schematic and its corresponding board, provided the board file
has been loaded before starting the ERC.
As a result of this check the automatic
Forward&Back Annotation
will be turned on or off, depending on whether the files have been found
to be consistent or not.
