It somewhat depends on how your device is structured. Most likely, you
could use something like this:
procedure(CCCfindTermShapes(instId termName)
let((termId)
termId=dbFindTermByName(instId~>master termName)
foreach(mapcan pin termId~>pins
pin~>figs || list(pin~>fig) ; cope with OA and CDB
)
)
)
This will return you a list of the pin figures for an instance. If you
want to find the center of each of these shapes in the coordinate system
of the containing cellView, you'd do:
pinShapes=CCCfindTermShapes(instId "D") ; for drain pin
centers=foreach(mapcar pinShape pinShapes
dbTransformPoint(centerBox(pinShape~>bBox) instId~>transform)
)
centers will then be a list of the center (centre for me ;-> ) locations
of all the pins on a particular named terminal.
Note that NONE of the code above has been tested - I just wrote it in
the reply without testing it.

thanks a lot Andrew.. but for some mos its showing three gates G for a single mos. Is there any way to get to it by only one G for each instance or we need to use code to skip other G for a specific instance.......

I can't see how anything could do this in a generic way (you could just
take the car() of the list - but that's completely arbitrary).

Ok Andrew thanks for your valuable suggestion i will use the code to do it..
