How to connect pins of different width?

[michele bergo]

I have made a controller for a zbt sram that has sa[17..0] and dq[12..0]. I
want to simulate the controller with a zbt sram model with sa[3..0] and
dq[3..0]. How is it possible to connect pin of different width without
changing vhdl source file?

Thanks a lot.

Assign sa(3:0) of the controller to the RAM model & similar for address.
leave the higher order bits unconnected if driving, or tie to a value like
'0' or '1' if driven,
so they have a valid value.
