How to define double vias in rules file for VCAR

PSRK

 Hi,

 I'm using the below constraint in the vcar rules file  before exporting. The VCAR is placing single via while routing.

    list( '("tsmc18rf" "M2_M1" "symbolic") t)

But I dont know the rule to keep double contact/via in the router .Please help me.

 

Thanks,

Siva

  •  Hi Craig,

    I referred to the use_via and use_array commands from the links that you have posted. My issue is solved now. I added these lines to my do file.

    select all nets
    define (group group1 (selected))
    circuit group group1 (use_via (use_array M2_M1 1 2))

    ##Standard Routing Command
    route 25
    clean 2
    route 50 16
    clean 4

    I was wrong with the rules file. Thanks for your response.
