Ext flash connection in top level block diagram

For Altera Cyclone III (3c120) dev kit, I have the following connection for ext_flash in my verilog top level:-

output [ 24: 0] top_fsa;

:

:

wire [ 24: 0] top_fsa;

wire [ 25: 0] top_fsa_alignment;

:

:

assign top_fsa = top_fsa_alignment[25 : 1];

:

:

.flash_tristate_bridge_address (top_fsa_alignment),

Can anyone please tell me how can I do this kind of connection in my block diagram?

My ext_flash in SOPC Builder setting is

Address Width - 25

Data Width - 16

Any help would be appreciated.

Thanks
