No, that's the number that doesn't change. Suppose I have: slot=2 slotdef=2:7,6,5 That implies there should be three pins on the symbol, with pinseq=1, pinseq=2, and pinseq=3. The pinnumbers will in this case be 7, 6, and 5, respectively. For PCB layout, the usual thing is to make pinnumber visible, because that's what the technician probing the board is going to want to know. The slotting mechanism automatically changes the number that is displayed in this case. > > You mentioned 'Pinlabel is for hierarchy'. I am lost on that one, > totally. If you have a symbol that represents a subcircuit, not just a simple component, the subcircuit schematic is identified by a source= attribute in or attached to the symbol, and the connections between internal nets and external "pins" are identified by pinlabel, using refdes= attributes on "IO" symbols on the internal schematic.
