How to connect pins of different width?

Discussion in 'VHDL' started by michele bergo, Aug 23, 2003.

  1. 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.
