How to make wire turns at 45� instead of 90 with autoroute?

autodeskguest

 

I have read that is not a good practice to let wires to turn at 90º. All

wire turns must be formed with a couple of 45º turns.

How can I use autoroute to do this automatically?

 

thanks

    What kind of clock rates are you running your system at?

     

    Unless you are running at very high clock rates (>>100MHz), or

    require very tight impedance control on your traces, then 45º

    is not necessary, and 90º will do just fine.

     

    There are some situations where bending traces at 45º helps

    route around obstacles but odd angles are hard for autorouters

    to deal with.
