Bagness Procs The bagness information is stored on a CellType public wire under the property $Bagness, but only when it is nontrivial (i.e., the wire is disconnected). For each such wire, it contains a list of bags of the pins that comprise that wire. Nodeness Procs The nodeness information is stored on a CellType under the property $Nodeness. It is unique for each (Decoration, TouchProc) pair, and consists of a list of the disconnected public wires of the cell. Returns the nodeness of cell, caching the information if necessary. ΚJ˜codešœ ™ Kšœ<™
