I'm creating a library object for the Atmel ATmega644. This chip is
available in PDIP and TQLP packages. The PDIV vesion has 40 pins, the
TQLP version has 44 pins. The additional pins of the TQLP version are
used for additional Vcc and Gnd connections.
How can I have one 'device', using one 'symbol' for both packages ?
I'd like to connect 1 'symbol' pin to multiple 'package' pins.
It looks like I get either a good PDIP variant and a TQFP with some pins
not connected or if the symbol has multiple Gnd/Vcc pins the TQFP is
fine and the PDIP has warnings about the unconnected pins.
