Hmm. This would allow for a neat upgrade. But symbols for the 44 pin package would be rather over-sized. How about this: * Start with a 'monolithic' symbol for the 44 pin package * The symbol for the 64 pin package is split in two. One sub symbol contains all the pins that this version shares with the '4 chip. And a second sub symbol for the pins of the additional ports. * The symbol for the 100 pin package is split in three. The first two for the pins that match the 64 pin version. And a third sub symbol for the rest. That way, the additional pins of larger versions can be placed out of the way of nets connected to the lower port pins. ---<)kaimartin(>--- -- Kai-Martin Knaak tel: +49-511-762-2895 Universität Hannover, Inst. für Quantenoptik fax: +49-511-762-2211 Welfengarten 1, 30167 Hannover http://www.iqo.uni-hannover.de GPG key: http://pgp.mit.edu:11371/pks/lookup?search=Knaak+kmk&op=get
