Routing Angle

archive

Hi, can we change the routing angle using skill, currently we can change it to "off, 45, 90", is there a setting in allegro that we need to change so we can route signal using other routing angle like "10" thanks

  • If you manually routed a 'stairstep' trace from point A to point B

    A----
           |
           ------
                   |
                   ------ B

    a routine could then skew the segments from 0/270 to 350/260, yes.
    Your path is now slightly shorter, which might cause other concerns.
    Naturally, more-complex paths would require more-complex code to achieve the goal. Something like a semicircle

    A--------
                |
                ------
                       |
                       |
                ------
               |
    B -------

    would require 'breaking' the vertical segment at the midpoint to yield two smaller segments that can
    be skewed, one tilted backwards the other forwards.
          
    Or maybe we're overcomplicating the problem? If you are routing these special traces manually why not
    simply turn Routing Angle to 'OFF' 

    In closing, a routine could be crafted to help you but its complexity would be in direct proportion to the
    complexity of your requirements and would definately require some fine-tuning - this is not something one
    cound crack out in a few hours.
