I only found the 7/14 symbol do you know the name of the other one? As I haven't tried the box yet, I tested it in the attached example. Even the netlist seems to be ok, as the power symbol is dominant over the net names inside the logic symbol. I'm not sure whether it is because of it was intented that way or just by happy accident. ;-) --------------netlist PCB------------- unnamed_net3 R1-2 U1-14 unnamed_net2 U1-1 U1-9 Vcc R1-1 C1-2 U1-14 U1-2 U1-5 GND C1-1 U1-3 U1-7 U1-6 unnamed_net1 U1-8 U1-4 ----------------------------- Note: U1-14 is connected to the R1-2, not to Vcc. regards Werner
