Yes, gschem supports heterogeneous symbols. Just set refdes (u101) the same for all parts of the same device. Further, if you'd like to have different labels for different symbol parts you can append lower case characters which are ignored by everything but are there for user convenience. (U101a, U101b, U101ioports, U53power, etc) -Lares On Thu, 8 Feb 2007 15:13:52 +0100 fricker <fricker@xxxxxxxxx> wrote: > Hi All, > > I am evaluating gEDA and came across one feature I am extensively > using today with a commercial EDA tool when dealing with large > components, like SOC, FPGAs and ASICs: heterogeneous symbols. > > I searched the doc, the mailing lists and the Web but could not find > how I could create and use such symbols with gschem and gnetlist. > > As Roger Williams defines it in his post: http://www.geda.seul.org/ > mailinglist/geda-dev6/msg00003.html > > > Heterogeneous devices are non-identical symbols that represent > > different parts of the same device for REFDES and layout purposes. > > They can be tied together by the same 'HETERO=DEVICE1,DEVICE2...' > > attribute on each device.
