'[OT]: Protel 99 routing'

I'm evaluating the Protel 99 and I want to route
a single side board. Is there any setting to allow
it to route the board and put the necessary jumper
when it can not complete routing as single side board?

From memory,  you have to add the unrouted track &  jumpers manually.

Scarp the auto-router and do it the old fashion manual way, you will
probably end up using less or no jumpers.
But no as far as I can remember you have to add the jumpers your self.

No way you can do that. I use Protel a lot and I still haven't found that
answer. In my oppinion it is better to do the layout by hand and interactive
route the board. You will get a better parts placement and a LOT less
jumpers. A two sided board, protel thought there are about 40 vias and 20
jumpers needed, but I have done it interactive and ended up with 5 jumpers.

That's the way I do it.

I had a Protel tech tip published once which was about using the top
layer for links. You can just auto/manually route the board and swap to
the top layer to run a link. When the single sided board is made only
the bottom layer is produced. When printing the top overlay, print the
top layer as well to see the links.

Tony,

That's the way I'm working this problem around and used to think that was an
original idea, :-(
The question was if Protel alone can auto route single sided boards and put
the links by it self. I think the answer to that question is no. Is there a
way to do it? If yes I'm very interested.

Best regards,
Mircea Chiriciuc

Put a bogus SMT part on top of the board, then
connect an entire copper plane on top layer of the
board to that part. Or use any better method you can
to force it to just route on the bottom.

The autorouter will try to route the entire thing
on the bottom layer, as it can't use the top, and
it will route mostly complete apart from a few
airwires.

Manually tidy the bottom routing a bit so the
airwires are few and short in length like links.

Then remove the bogus part and top plane, and press
continue routing, it will instantly route each
airwire to a short top trace, just like a link,
and without changing the bottom layer. :o)

Obviously set via pad size and drill to be the
same as a standard pad. Job done. :o)
