  • Hi Bob,

    Using non-default rule for creating wider wires for some specific case,  is well understood. Kari has also explained in a tutorial how to create those rules in a LEF file .

    But it is still obscure to me what we should do if we want to have "via arrays" on these wires. By default, it seems we get the default (single) via at each layer chnage.  How can we get the maximum possibe array of vias (like the special vias of the power/ground nets) ?

    Could you tell a bit more ?

    Thanks
