Ext flash connection in top level block diagram

Altera_Forum · ‎07-12-2011

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

Carid

Draw a bus wire from the sopc component port and leave it unconnected.

Double click it and rename it as: " top_fsa[24..0],dummy "

Add another bus wire with both sides unconnected and name it top_fsa[24..0], then connect on side to an output pad symbol

Hi Cris72, thanks. But I wish to clarify your answer.

Did you mean draw 2 wires using 'Diagonal Bus Tool' and both also named as top_fsa[24..0]? Sorry it doesn't seem very clear to me.

The orthogonal bus tool is what I meant.

I attached a picture for your convenience.

I hope I correctly understood what you want.

Hi Cris, thanks for your screenshot. But I think it should look like this. I tried and it succeeds.
