| * Setting both ''asym_up'' and ''asym_dn'' to zero implies that the vias have symmetric surround. If either of these are non-zero, then we assume that we are using asymmetric vias. | * Setting both ''asym_up'' and ''asym_dn'' to zero implies that the vias have symmetric surround, and the ''up'' and ''dn'' parameters are used to determine the surround value. If either of the ''asym'' parameters are non-zero, then we assume that we are using asymmetric vias and the ''asym'' parameters are used. |
