J1 pins are pas nets: U1.1 U1.3 U1.4 U1.5 U1.6 U1.8 J1.A4 U1.9 U1.10 U1.11 U1.12 U1.13 U1.14 U1.15 J1.B3 U1.16 J1.A4 First: J1.A4 is used twice in effect reducing the nets to two nets U1.1 U1.3 U1.4 U1.5 U1.6 U1.8 U1.16 J1.A4 All pins pas U1.9 U1.10 U1.11 U1.12 U1.13 U1.14 U1.15 J1.B3 pins include types such as pas, in and pwr For the second net arcording to the drc2 matrix 1) pas may connect to pas, in or pwr 2) in may connect to in or pwr There for DRC2 thinks that there are no connection errors. >From my reading of DRC2 it tests for 1) Non numbered parts 2) Duplicate references 3) One connection nets 4) net pin types 5) slots 6) duplicated slots 7) un-used slots I would expect complaints about duplicate slots and un-used slots. Not about the way the pins are hooked together. One obvious weakness is that the test schematic connects, V+, V-, VL and GND together. These are all type pwr and thus according to the matrix they may be connected. I think this is a weakness of pins not being heavier.
