Automatically route the net for all devices which is selected in Layout.

Sarvani

 Hi all,

          I am working on Layout XL. When I select the a net on layout then it will automatically route. For example in layoutXL 3 devices has "net1" connection. If I select "net1" then "net1" routing will be automatically done for those 3 devices.  Is there any command for this directly or need to write code for this. Please suggest me on this.

Thank you,

sarvani

  •  Sarvani,

    One way I've done this in the past is to start the router with a "do" file (there's an option to do this on the export to router form), with something like the following contents:

    define (class ALLNETS *)
    #
    circuit class ALLNETS (use_via M2_M1 M3_M2 M4_M3 M5_M4 M6_M5 (use_array M2_M1 1 2 ) (use_array M3_M2  1 2) (use_array M4_M3 1 2) (use_array M5_M4 1 2) (use_array M6_M5 1 2))
    #
    set enforce_use_array_rule on

    You'll need to give the right via names there - this is telling it to use 1 by 2 via arrays for all nets.

    Regards,

    Andrew
