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.

 

Andrew:
We rename terminals in the symbols often. Almost as often the cdsTerm
label is not updated. I wrote the following to try to help the
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
next thing I will do is write something that allows the user to click
on the terminal and then the cdsTerm label to update them but that is
quite lame.

;printf("ctu()\n")

;
; If terminals are renamed in the symbol the
; corresponding cdsTerm label is not updated.
; This program aims to help remedy the situation
; by giving the user the option of updating
; the cdsTerm label names to match the parent
; pin names.
;

procedure(ctu()
prog((cv label_name pin_name)

;get cv dbid for the current open symbol view
cv=geGetWindowCellView()

when(cv

;make sure the cell view is a symbol
when(cv~>cellViewType == "schematicSymbol"

;find the cdsTerm label in the shapes
foreach(shape cv~>shapes
when(shape~>theLabel && rexMatchp("^cdsTerm"
shape~>theLabel)

;get the label name
label_name=nth(1 parseString(shape~>theLabel "\""))

;get the pin name
pin_name=shape~>parent~>pin~>name
dprint(pin_name)
dprint(label_name)
when(label_name!=pin_name && pin_name!=nil &&
member(pin_name cv~>terminals~>name)

dprint(pin_name)
dprint(label_name)

when(cv~>mode!="a"
;checkout call
ddAutoCheckout(ddGetObj(cv~>libName cv~>cellName
cv~>viewName))
;change mode to editable
schHiChangeEditMode("a")
) ; when

;checkout failed, error out
when(cv~>mode!="a"
error("View could not be opened for edit.")
) ; when

;make the cdsTerm label the same as the pin name
shape~>theLabel=strcat("cdsTerm(\"" pin_name "\")")

) ; when
) ; when
) ; when
) ; foreach

;check&save cell view
dbCheck(cv)
dbSave(cv)

) ; when

return(t)

) ; prog
) ; procedure

 

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...

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

 

Andrew:
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.

 

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.
