Re: gEDA-user: subcircuit definition and channelised design

[Geoff Swan <shinobi.jack@xxxxxxxxx>]

   Lots is possible, but I'm not sure how you would best go about it.
   gEDA's bus support is almost non-existent... it is just a graphical
   nicety, and relies upon named nets. (I vaguely recall that Altium buses
   can work like this too if you want)


   I haven't really used busses properly in Altium - as you described,
   I've primarily used them just as a graphical nicety while explicitly
   naming all the connected nets. There may have been a few cases where I
   named the bus and then connected nets were given the bus prefix, or
   something like that. But at the time I was just experimenting and
   didn't really need or find this sort of functionality added much value.
   (I imagine with a number of 32/64 bit busses something that removed the
   need to individually name nets would be handy though)

   In terms of the channelisation functionality my current thought is that
   I may be able to augment the gnetlist pcb backend to recognise
   something similar to a bus notation and recognise when a
   symbol/subcircuit needs to be replicated. (btw - I haven't yet started
   looking through the gnetlist backend sourcode or doco so if this sounds
   like something impossible - feel free to give me a heads up :)

   cheers,


   Geoff Swan
