RE: gEDA: [blarson@blars.org: Bug#163584: geda-gschem: need generic transistors, component scale, lable orientation]
Hi Xtian and all,
By "original spec" in line 2 of your mail, do you mean 1.5 times bigger as
the IEEE spec, or 1.5 times bigger as the current symbols in gschem ?
With regard to 200 mills --> 300 mils the following: several connectors (or
headers) in gschem have a different pin spacing as the IC symbols created
with gmk_sym.
So you have to zig-zag up and down to connect a 8 bit databus to a 20 pins
header for instance.
The use of busses is still not advised by the various docs on this subject.
What does IEEE say about this issue ?
With kind regards,
Bert Timmerman.
