I really like the "Wire stubs and names" feature/function in the "Create" dropdown menu in Schematic Editor, but is there a similar way to add pins with pin names?
Not quite - there is a Create->Mapping Schematic which (sort of) does this - it's primarily intended to create a schematic which maps from one cell to another.

In reply to Gang Liu:
Which? The create wire stubs or create mapping schematic? There aren't any built-in procedural versions of either (only the functions that bring up the form). I did write this some time ago for creating wire stubs, but it's not terribly smart about the placement of the stub:

Create wire stubs for any instance pin which has a net
name, but no existing wire.
SCCS Info: @(#) abCreateWireStubs.il 07/07/00.17:01:10 1.1
(procedure (abCreateWireStubs @key (cellView (geGetEditCellView)) (stub 0.03125)
(labelJustify "lowerLeft") (labelOrient "R0")
(labelFont "stick") (labelHeight 0.03125) (debug nil))
(let (transform pinCentre wireEnd netName lineList)
/* loop over all the instances which are not pins */
(foreach inst (dbGetq cellView instances)
(when (equal (dbGetq inst purpose) "cell")
(setq transform (dbGetq inst transform))
/* Now go over each terminal, and each pin for that terminal */
(foreach instTerm (dbGetq inst instTerms)
(foreach pin (dbGetq (dbGetq instTerm term) pins)
/* If there isn't a piece of wire over the pin anyway
add the stub */
(dbGetq (dbGetq pin fig) bBox)
/* calculate the coordinates for the stub */
(dbGetq (dbGetq pin fig) bBox)
(if (equal (dbGetq instTerm direction) "input")
/* transform them accordingly */
(setq pinCentre (dbTransformPoint pinCentre transform))
(setq wireEnd (dbTransformPoint wireEnd transform))
(setq netName (dbGetq (dbGetq instTerm net) name))
/* create the stub wire */
cellView "draw" "" (list pinCentre wireEnd) 0.0 0.0 0.0)
/* label it */
(when (car lineList)
cellView (car lineList) wireEnd netName
labelJustify labelOrient labelFont labelHeight nil
(printf "Added stub to %L for pin %L of %L\n"
(dbGetq (dbGetq instTerm net) name)
(dbGetq instTerm name)
(dbGetq inst name)
I've written other code to determine the side that a pin is on which could be combined with this to make it smarter about which direction it draws the wire -
but I've never joined the two together.
Thanks a lot Andrew!
I tried your script and it works pretty well. Probably someone took your code and integrated it in cadence, so now we have this function from the cadence menu :)
What I was looking for was to add pins, with proper names. For instance, if I have a instance symbol in my schematic, I want to create a pin for each terminal of that symbol with the same name.
I found a solution from the following page:
Thanks to all the people who share their knowledges.
