Hello,

thanks a lot for your answers.
indeed, i misled the using of dbCreateInstTerm. thanks you for the
lights.

I used dbCreatePin to create pin in my pcell. I did:

net_name =3D "PLUS"

net_id  =3D dbMakeNet(pcCellView net_name)

term_id =3D dbCreateTerm(net_id net_name "inputOutput")

PinPlus =3D dbCreateRect(
					pcCellView
					Layer
					list(0:0 ShapeWidth:ShapeLength)
					)
dbCreatePin(net_id PinPlus net_name)

dbAddFigToNet( PinPlus net_id )

dbCreateLabel(
			pcCellView
			Layer
			ShapeWidth/2:ShapeLength/2
			"PLUS"
			"centerCenter"
			"R0"
			"roman"
			0.01
)

but i can not extract any pin information in icfb.

Actually, i'm writing a skill that should be able to list all pins of
level 0 and level -1. In this pin information list, i would like to
display the name of instance, its location and real location of pin.

but just creating a pin and finding information like real location
(and not location in the master) is a little bit hard for me (;_;)

i thought adding a label would be easier, but it's not the case.
i thought adding a fig would be helpful, but it's not the case either.

So i really don't know how to create my pin list information.

could you help me please?

Thanks ,

b.
