attach label to a pin as a 'children'

Sorry for necroposting, but i found this page very useful, so i adding my code to automaticly generate labels on all selected pins

foreach(X geGetSelectedSet()
 net = X~>net
 disp=dbCreateTextDisplay( net X list("TEXT" "drawing" ) t centerBox(X~>bBox) "centerCenter" "R0" "roman" 2 nil nil t nil t "name" nil)
)

 disp=dbCreateTextDisplay( net X list("TEXT" "drawing" ) t centerBox(X~>bBox) "centerCenter" "R0" "roman" 2 nil nil t nil t "name" nil)
)

Very simple and useful code, I was wondering if it was possible to use dbCreateTextDisplay to create a label with not just the net name, but say with the area value of a rectangle also?

so passing a string value instead?  

for instance

area=5

string = sprintf(area "%f" area)

disp=dbCreateTextDisplay( net X list("text" "drawing" ) t centerBox(X~>bBox) "lowerCenter" "R0" "roman" abs(dy/3) nil nil t nil t string nil)  

This gives me an error, but perhaps I am missing something.

If you want to create a label, use dbCreateLabel. dbCreateTextDisplay is to display the value of a database attribute or property on an associated object - it's not to display arbitrary text (the benefit of a text display is that if that associated attribute value or property value changes, the text displayed changes without needing to do any updates).

By the way, the dynamic display feature in Virtuoso Layout Suite also allows you to dynamically show the area of an object as you hover over it...

Andrew.

Yes, I am aware of the dynamic display, but it is more useful to have the area attached to the object and visible at all times when floor-planning.

I will try and play around with dbCreateLabel for passing a string in for the area.  Thank you for pointing me in the right direction.

Andrew, I had something working very well, but I was trying multiple iterations of things, and by the time I restarted cadence after a crash, the code I was using started to give me errors.

*Error* dbCreateLabel: Invalid cellView - db:0x218a5c9a

For a more complete picture here is the code I am working with now.... It is a simple bindkey that will grow a rectangle by a fixed amount and maintain the area. That part is fine, 

It then should create labels for the Net Name, Area, and Length and Height of the shape.

Right now only the Net Name is passing through.  It seems to be stalled at the dbCreatelabel portion.  but I had everything working for a few days.  Thanks in advance.

Your code doesn't the variable cv anywhere, so you're reliant on that having been set (and set correctly) before you hit the bindkey. Simplest solution is to put the line:

cv=X~>cellView

before the first dbCreateLabel line.

By the way, your code breaks if the selected shape has no net information - so you might want to change it as follows. Note that I added some comments with "AB" above some parts that I had concerns about (for example, the setting of the label type to ILLabel makes no sense - that's for interpreted SKILL labels, and these are not SKILL expressions but strings containing numbers. That will have no effect at level 0, but if instantiated, it would mean the label has to be evaluated every time it is displayed, which is pointless.

Finally, the code rather strangely has nested loops where the outer loop iterates over geGetSelectedSet and the inner loop iterates over geGetSelSet - both will return the same set of objects. I don't know why it's doing this, but if you have two rectangles selected, then it seems to stretch one and add labels on the other - I doubt that's what you want!

Andrew.

Hi,

    while doing layout If pin labels are moved away from its respective pins... How to move those pin labels back to its respective pin location? I want to write a skill code where i want to select those labels and to press a bindkey then i want labels move its respective pins..?can you please help me on this..
