Cadence Design Entry HDL connecting different widths buses

Hi!

I use Cadence Design Entry HDL 16.5 for schematic entry. What I want to do is to connect four blocks(each has 16-bit bus input) to 64-bit bus.  I know that for connecting single net to bus I use "tap". What component should I use to connect shorter bus (16-bit) to wider bus(64-bit)?

Regards,

Krzysztof
