Vince,

I have been laying out PCBs for nearly 30 Years.? I have used just a few.? They are really a learning curve.

There are some really expensive packages that I have not used (Mentor?).? I would put little faith if they claim great auto-routing?

You might get results with an auto router, I never have.? I have watched it put traces down until it gets in a corner.

Then it "Rips Up and tries again", kind of sadistic to watch!

If you had lots of space on the PCB, maybe let it go, and then? finish it manually.

The real secret is to really spend time on a good schematic.? And when the Design Check says "you got problems",

you better heed the warning and fix the problems.?

Will any of these packages that have been mentioned do automatic routing?? Or are you required to do all the runs manually?

Vince.

Lt Spice is a circuit simulator.? Not for Layout of PCBs.? Use one of
the online PCB programs folks have been discussing here on the group.
Look back through the posts on PCB Layout Software.? Any of them will
require a learning curve.

For instance, that circuit uses some small SCRs.? Not a real popular
part, you might get to make the Model (s).

There is a schematic model and its matching PCB model.? Start with the
schematic program and create a nice schematic before going to PCB.? It
will transfer its connections (netlist) to you PCB.?? It will find many
mistakes (inconsistancies between schematic and layout).? If you are
real careful, you can make PCBs that are correct the first time!

PCB layout is Really Fun!? Better than crossword puzzles.

If I wranted to build a circuit like this one is there a software to
help me layout a perfboard for the circuit.? I have LTSpice but I
don't see anything to layout a perf board in it. It just may be that I
don't know where that feature is in the software.
