Virtuoso XL Auto Router(routing width input ?)

Amar Kumar

Hi All,


I am using Auto Router option(Virtusos XL -> Route -> Automatic Routing) for the layout routings.However the tool is routing by taking the minimum width of the metal layers.

Is there any way to customize the routing width of each metal layer in Auto Router tool?

I tried searching the option for specifying width input in the Auto Router GUI ,but i could not find it.I have little idea that the width can be controlled by creating a customized "constraint group".But not very clear about this.

Please suggest me some way to do it(I am using Cadence 6.1.6 version).


Thanks In Advance,

Amar

  • I Amar,

    I think you can customize the width of each metal in the "wire assistant" .

    To open the wire assistant click on : Window -> Assistants -> Wire Assistant

    Then you can change the width of each metal, the routing direction, the via etc etc ...

    Regards
