Re: gEDA-user: Is gnetman available for download anywhere?

Hi All,

Happy Hew Year!!!

[snip]  There is also the updated logic to allow gschem to recognise the
connection between a bus pin and a bus, disallowing net->bus pin
connections etc..

Currently, the stocked "verilog" netlister already implemented
the BUS pin, by assigning a pinnumber attribute in a form such
as "BUSA[31:0]". If you implement your way of BUS pin, please
do not break the usage as in current "Verilog".

Best Regards,
Paul Tan

I'll try to get this fixed for the next development snapshot. I've got
some code which fixes up the drawing of bus type pins to make them, and
their cues fatter.

There is also the updated logic to allow gschem to recognise the
connection between a bus pin and a bus, disallowing net->bus pin
connections etc..

I'm almost done with the above changes, however I'm not so sure where to
stash the option for switching a pin to / from being a bus pin.

Since the stock gnetlist doesn't grok buses, I don't want to make it
_too_ obvious, so that we don't mislead users into thinking they will
get connectivity by this method.

Shortcut key?
Menu item?
Context (popup / right click) menu item?

One other idea I was toying with was the possibility of extending /
specialising the multi-attribute editor to edit more properties of an
object.
