I was looking for related questions here, and the closest one I could find was this one: Industry Practices for Schematic Design?
However, it does not address my specific question, so here goes: I am not an EE and am just trying to learn Eagle so I can break my reliance on ExpressPCB, which I have found to be okay for simple projects, but being stuck with their proprietary format, tool, and fab no longer appeals to me.
In my past, limited experience with making schematics, I lay out the pins in numerical order, which is typically pin 1 to (N/2) from top to bottom on the left, then pin (N/2+1) to N from bottom to top on the right.
While that's fine and all, I'm now laying out a board for the MCP73123 to test a LiFePO4 charger (because of my other post here) and noticed that in Microchip's datasheet, they lay out their schematic like this:
Personally, I would think this is the way to do it, since CAD/CAE tools know what the correct pin assignments are anyway, and this looks a heck of a lot cleaner in the schematic since related pins are within close proximity of each other.
So my question is simply, do you experienced PCB designers typically do this, or do you go with the numerical-order approach? What do you consider to be the pros / cons of each approach. Also, is there another methodology?
