Is it possible?

Former Member

Good Evening Everyone,

 

I drew a simple schematic with standard LM317T power supply, a 20-pin encoder chip and a 5 pin Receiver chip. I admit I used the auto route feature (trying to save time) and converted it to a board as usual. I went ahead and made my pcb only to find that the routing was completed incorrectly!

One of the nets went directly from one pin on the encoder to one pin on the Receiver chip. I rechecked by schematic. The board should connect these two pins, but instead it goes to a completely different pin on the Rx. Also, my schematic shows clearly that pin #2 should have no connection made to it at all, but there is a connecting net to pin #2, while pin #3 is left unconnected on the board. I have checked and there are no jumper wires I am over looking. It seems to me that the program V5.11.0 just didn't convert it correctly. Is this possible.

Thanks,

    I don't think so.

     

    Most probably the device definitions are simply wrong (Rx mirrored?).
