Problem with create Auto Via option.

Hi All,

I am using Cadence tool IC6.1.5 version . In the technology library there are different types of vias like (M2_M1a, M2_M1_FBD,M2_M1_PBD, etc,.) .  If I use auto contact between M2 and M1 with option under Via Definition as "M2_M1_FBD" or "M2_M1_PBD". It will place the via with via Definition as "M2_M1_FBD" or "M2_M1_PBD" , but has the parameters as Minimum Rules which is for "M2_M1a" .

I want the selected vias with corresponding Viasdefs not the minimum rule parameters.

Please tell me how to overcome this issue.

Thanks ,
