Eagle routing
Hi transistance,
impatience is something Turks have to live with. They are just created that way.
Going to electronic design you must defeat your impatience. The program can not do the mental work for you. A board design, no matter how many components are used, is always artwork. The program however doesn't know of any art.
Here is a good advise to design circuit boards without lots of stress and confusion (because of the heavy load of airwires): This is an easy step-by-step-method.
Draw a part of the schematic, say 10 components and connect them. Then create a board, just typing "board;".
You should also already have considered what the final board should look like, e.g. PCB-connectors and terminals at the outer edge of the board and know the side they should be placed. (You certainly don't want terminals pointing to the front end of a board which also contains indicator LEDs and switches.
)
Place the few components in a way to reduce intersections and crossings already with the airwires. Then route that part manually. Don't do it too sohpistacated (e.g. using a routing grid size of 1/160inch, 1/20inch will to in many cases), since you will decide to rip up one or another trace for rerouting later.
With those 10 components you know exactly their relation within the circuit and can place them logically and practically.
Then step over to the schematic again and repeat the procedure until you are finished.
You'll see success at the end with a good looking design.
My philosophy about electronic design has always been that: A circuit does not only have to function properly; it must look beautiful too.
As already mentioned placing a part somewhere else (not too far from the others connecting to it) or just rotating it might solve many problems. Move or rotate and use "ratsnest" right away.
It is disgusting and frustrating placing parts on a board, working for hours to route them to finally find out that a decoupling capacitor (connected to a voltage regulator IC) was placed at the opposite end of the board, making a good detour to its destination, and being worth - NOTHING.

P.S. I know a lot about Turkey and its people. I've lived in Turkey for more than five years. Concerning patience there seems to be a "one-way" impatience. Think it over!
