How to convert Wire to a Geometric wire

Ferdz

It was requested that I should use "geometric wire" instead of "wire", problem is I was using "wire" for routing from the beginning it will be a lot of work wasted if i re-do the routing.

Is there a way or a script that converts wire to a geometric  wire?

 Please help.

 

regards,

Ferdz

  • Hi Andrew, In Using Mixed Signal On Top (MSoT), One of the cadence guy in our company recommend using Geometric Wires for routing power/ground and special nets, he said that if you use "Wire" the wires and vias will be recognized as regular vias and wires and will be removed by nano route in the EDI.

    Yes it is true that on 6.1.6 the geometric wire options has been removed but you can enable it by using envSetVal( "we" "mixedSignalWireEditingEnvironment" 'boolean t )

    If cadence is trying to get rid of this Geometric wires, then there should be a way that if you use Wire you have an option to lock them so that EDI would not touch them.

    PS: Even if you set the "route status" of the Wire/via to "locked" some of my colleague here says that it is still removed/deleted by nano route. Regards, Gerald
