Re: Cheap Schematic Capture



Paul,
I wouldn't concur with your statement of needing the same program. For
many years I used OrCAD schematic with PADs, then Protel for Windows
replaced the OrCAD, still with PADs. Many years ago I used OrCAD with
Maxi-PC. You do need a progam that will export a simple compatible netlist
of one form or another. The more critical part is the synergy between the
schematic symbols and the PCB footprints. That synergy is buitl itno the
symbols simply by exchange of information and the standards used for pin
numbering on any devices not already covered by an accepted standard. (i.e.
SOT-23s, DPaks, SOT-223s, etc. The parts where some pin numberings differ.)
For the OP to learn the package he obtains, apply all the standards
correctly, get matching symbols and a compatible netlost output would be a
tall order. Not impossible but surely a lot slower and riskier process than
just having the PCB designer do it. The PCB designer is undoubtedly familiar
with his own tools bringing much more sped and value to the process.

Hi

I'm looking for a cheap (or free!) schematic capture package that can
output in PADS format. I'm not the layout guy but it will certainly
save him time compared with me drawing out the circuit in a normal CAD
package. Pin count around 1000 at present.


You really need the schematic program that he's using, along with the
libraries. Otherwise the components almost certainly won't match up, and
he'll have to spend a lot of time converting them. It's a real pest that
there's practically zero interoperability between different CADs, and one
place where a European directive would be useful, if they could be trusted
not to screw it up.
