change cdsTerm labels

Are cdsTerm labels associated with the terminals at all? I would like
to automatically update all the cdsTerm labels in a symbol so that they
match the terminal names.

Erik,

The automatically generated cdsTerm() labels are attached to the shape making
the pin (see the ~>parent attribute of the label). However, this is not
necessary for the cdsTerm() labels to function, it's just how the automatic
symbol generator does it (it means that the label will move when the pin is
moved when the symbol is edited).

To find the labels, you'd merely need to look at all the shapes in the
cellView, find those with an objType of "label", and a labelType of "ILLabel",
which match cdsTerm.*. The important thing is the name of the terminal passed
as an argument to cdsTerm has to match the name of a terminal on the symbol.

Regards,

Andrew.

We rename terminals in the symbols often. Almost as often the cdsTerm

situation but it is a total failure as it only fixes the case when the
cdsTerm label is different than the terminal name and not the case when
the terminal name is different than the cdsTerm label. I guess the

on the terminal and then the cdsTerm label to update them but that is

Erik,

Surely the case where the terminal name is different than the cdsTerm label is
the same as when the cdsTerm label is different from the terminal name? In
other words, non-equality is commutative...

Yes, but if one changes the cdsTerm label I can get the original
parent~>pin~>name. If the terminal is changed I don't know which
cdsTerm label to update.

OK, I understand. Probably what I'd do is look for any cdsTerm labels which
don't have corresponding terminals, and delete those. I'd then look for any
terminals which don't have corresponding cdsTerm labels, and then create new
labels for these.

That way, any manually moved/placed labels will stay in the same place, but
you can auto-add the missing ones, and cleanup any incorrect ones.

Regards,

Andrew.

OK, I am trying to just delete all the cdsTerm labels and add them all
again. Any advice on how to create the parent structure so that the
cdsTerm moves when the terminal moves? I can do the attach manually by
doing a query on the cdsTerm label and then hitting attach and
selecting the terminal. How do I do the attach without using the
mouse to specify where to attach?

cv=geGetWindowCellView()

;delete all cdsTerm labels
foreach(shape cv~>shapes
when(shape~>theLabel && rexMatchp("^cdsTerm" shape~>theLabel)
dbDeleteObject(shape)
) ; when
) ; foreach

foreach(term cv~>terminals

foreach(pin term~>pins

shape=dbCreateLabel(cv list("annotate" "drawing8")
car(pin~>fig~>bBox) strcat("cdsTerm(\"" term~>name "\")")
"centerCenter" "R0" "stick" 0.0625)
shape~>labelType = "ILLabel"
;hiSelectTextByLoc(hiGetCurrentWindow() shape~>bBox)
;schiAttachLabelAddPointCB(hiGetCurrentWindow()
centerBox(shape~>bBox))
;schiAttachLabelAddPointCB(hiGetCurrentWindow()
centerBox(pin~>fig~>bBox))
schiAttachLabelDoneProc(hiGetCurrentWindow() t
list(centerBox(shape~>bBox) centerBox(pin~>fig~>bBox)))

) ; foreach
) ; foreach
 
schGlueLabel() is probably the function you want.

Andrew.

Andrew:
Yes! schGlueLabel() is what I was looking for. I have a curiosity now
however. If I create a schematic with terminals (a, b, c, and d) and
do a Design->Create CellView->From CellView to generate a symbol it
creates the parent~>pin on the cdsTerm label so that the label moves
when the pin is moved in the symbol.

If I change the name of pin a to newa and run the code to delete the
cdsTerm labels and add them back and then schGlueLabel I see that the
cdsTerm for the newa pin says cdsTerm("newa") as I would expect and the
label moves when I move the newa pin in the symbol.

What I don't understand is that if I select the cdsTerm("newa") label
in the symbol and do a car(geGetSelSet())~>parent~>pin~>name it still
returns "a".

In addition I am trying to get the justification and orientation of the
labels that correspond to the pins in the symbol (not the cdsTerm
labels but the actual pin labels). There is no way to determine the
pin label from the pin is there? If not, I will have to get search all
the shapes and match the theLabel name with the pin name.
