The hidden linkage is the pin mapping in the package. The package automatically appears in the board view when the symbol is placed in the schematic. There is no pin location information visible in the symbol. ... > What I am mentally missing is the linkage between the schematic, and > the terminals of the packages footprint which carry no labels, since > in this application, the mechanical location of the device on the > board is very important. A boots-first approach works well here, since the schematic and layout contain no magic smoke. If you just whack all your components into the schematic, _and_wire_them_up_, then little yellow "air wires" will appear between the package pins on the board. (Again, the board is only one mouse click away when you're in the schematic editor, so flipping back and forth, as you muck with both, is trivial. Those "air wires" allow you to verify which pin is connected where, thereby confirming the correlation with the symbol, by simple observation. In the future, if there's so much on the board that picking the right wire is problematic, then try using the "i" Info tool in the schematic. Click it on the desired wire. (The right hand wire in yesterday's demo schematic shows as "N$1") Click the "Board" icon on the horizontal toolbar, and you flick to the board layout. Select "i" there also, and click on either of the two "air wires", to positively identify the connection. Now we can't go wrong, at least not without a supreme effort. ;-) ... > But today I have a termite company installing new, kill em all, baits. > That is something else WV apparently has a surplus of, termites, in 22 > years this will be the 3rd attempt to nuke them. > > Thanks Erik. No worries. :-) I should really renew my termite defences too. It's a bit late once they're in.
