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.
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.
