Auto routing in Allegro16.0

[angel]

hiii all,

Can anyone help me in autoruoting in allegro16.0
I have routed PCB's manually only.
So i am not familiar with the constraint settings which are to be given while auto routing the board.presently i'm working on motherboard.
it needs to meet with several constraints like etch length,impedence etc.

expecting reply soon..

In V16.0 you can either use route automatic or route custom, Route automatic is the easiest and keeps you in the allegro environment, route custom takes you into the spectra environment which is completely different and has its own help files. Which im afraid would take too long to go into in this post. Personally I would route the critical tracks like matched length and impedance first then fix them then run route automatic, that’s straightforward enough.
