Смотрите команду circuit: relative_length_descriptor - allows length to be specified relative from one fromto to another fromto within the same group. This circuit rule only applies to groups. Use the relative_length rule to constrain the lengths of fromtos in a group relative to the length of a reference fromto. You specify the reference fromto and the delta and tolerance values used to calculate the relative lengths of the other fromtos. The length of the reference fromto is the value of the minimum length rule at the fromto or group level, if assigned, or the routed or Manhattan length.
