How to use skill change wire width and color in Virtuoso Schematic Editing ?
width : narrow change to wide(0.0625) or wide change to narrow
color : cadetBlue change to red
A new API was added for this in IC616, schSetWireColor(). There's also setSetWireLineLineStyle (and there are schGet equivalents of the schSet). Before IC616 there was no API (you could reverse engineer the group storage mechanism, but I wouldn't recommend that in case we change the storage mechanism at some point). You didn't mention the version you're using.
If you have a wire in wireId and want to convert from narrow to wide (you can tell it's narrow by seeing if wireId~>objType=="line"):
dbConvertLineToPath(wireId 0.0625 "roundRound")
To go the other way is a little more complex because there's no direct conversion function. It would be:
procedure(CCFconvertPathToLine(wireId) prog1( dbCreateLine(wireId~>cellView wireId~>lpp wireId~>points) dbDeleteObject(wireId) ))
This returns the new objId of the narrow wire.
And it would be schSetWireColor(wireId "red") to set the wire color (or colour for me ;-> ).
In reply to Andrew Beckett:
It's quite useful for the code from Andrew.
In case you have a label attach to the wire you want to edit.
There is no problem for using dbConvertLineToPath(wireId 0.0625 "roundRound") to convert line to path.
but from path to line, some code need to be added to keep the label, as:
lineId = dbCreateLine(wireId~>cellView wireId~>lpp wireId~>points)
;move the label from path to line foreach(child setof(x wireId~>children and(x~>objType == "label" x~>lpp == list("wire" "label"))) schGlueLabel(child lineId) );foreach
