How to find and print out the pins of schematic using skill

Hello,

I am not sure whether this is what you are looking for, but you can get the locations of the pins in a given symbol like this:

cell = dbOpenCellViewByType("libName" "cellName" "symbol" "schematicSymbol" "r")
warn("For cell %L, library %L\n" cell->cellName cell->libName)
foreach(term cell~>signals~>term
    termCenterPt = centerBox(car(term~>pins~>fig)->bBox)
    warn("Terminal %L location X = %n Y = %n\n" term~>name xCoord(termCenterPt) yCoord(termCenterPt))
);foreach

This is of course their location in the cellview, in case you need to operate on instances in schematic just transform these coordinates.

Thanks Peter, i tried it but it didn't works...i want the pin names

suppose for above cell names as i browse it...the power pin and gnd pin should reflect

as VDD1 GND1

regards

If you want the terminal names of a schematic, use:

cv=dbOpenCellViewByType(libName cellName "schematic")
termNames=cv~>terminals~>name
dbClose(cv)

Thanks Andrew, is there a way where i can differentiate between power, gnd and io pin and report them simultaneously

if am using above command...it just list out all pin names

or any example to understand

If the Signal Type has been set when the pin was created to "power" or "ground" (this is often automatically set based on the name) - select the pin and do an edit properties on it to check - then you can use this:

  termNames=setof(term cv~>terminals member(term~>net~>sigType '("supply" "ground")))~>name

(note, the database stores the "power" signal type as "supply").

This is the only indication in the database as to the intent of the signal - otherwise we have no way of knowing whether something is for power or ground.

Thanks Andrew!!!!!

Andrew,

i tried below way-

but am not getting the desired supply pin in box...apart from that all other options are working fine.

can you please help me with that

Sorry to be blunt, but I'm amazed after all these questions where you ask questions about implementing UI (both this and under your other account name), you still seem to be unable to do basic debugging. There are a few things wrong here:

1. The callback is on the Pwr_ports field, which means you have to enter something in that field and then move the focus outside to trigger the runpwrpin function to be called. So you'd type something there, click outside, and then it will run (which would be a rather odd use model). Presumably you would have either a button on the form or have it called once the lib/cell/view are completed (probably not a good idea to do that as it would keep re-reading things as you browse to the right cellView).
2. Even then, it fails with: *Error* let: local bindings must be a proper list - libName . This is because the let() statement is not correctly written in the callback function (hint, you could test this also by calling runpwrpin(hiGetCurrentForm()) in the CIW).
3. If I fix the local variable list, it also fails because you're trying to set the value of a string field to a list - termNames will be a list:
   *WARNING* Form 'abImportParasiticsForm', field 'Pwr_ports': Bad value ("VDD1").
   Must be a string.

Fixing the callback function to be this solves this (a bit of indentation in the code would help, as I keep saying):

procedure(runpwrpin(form)
let( (libName cellName termNames cv)
libName = form->lib->value
cellName = form->cell->value
cv=dbOpenCellViewByType(libName cellName "schematic")
termNames=setof(term cv~>terminals member(term~>net~>sigType '("supply")))~>name
form->Pwr_ports->value = buildString(termNames)
)
)

Note this still requires you to type something into the "Power Pins*" field and then change focus to trigger the callback; I'm not going to fix your UI code.
