I prefer to use actual pinouts in my schematics for two reasons: It
helps you with chip placement because naturally you will tend to place
symbols and lines to get the fewest line crossings. Going to layout
after you have already decided the best general position for parts
makes it much easier. The second reason is that later on it will be
easy to look back to a schematic that has a similar layout as the
board and the same pinouts.

Hello!
I have done some symbols (microprocessors etc.) using the djboxsym
tool and I have put the signals as they are located on the real chip
(i.e. correct pin number order).
I have now looked at some of your schematics and see that some of
you have grouped the signals more logical (i.e. PA0-7, VCC, GND
etc.) together..
This seems very handy when drawing the schematics but I wonder if
there are any problems with this method?
As I understand, as long as you define what chip type it is it will
be resolved and correctly translated once you generate the PCB.
Best regards,
Peter
