Usage of TriState bridge in Qsys

Hi,

I have system in which SDRAM and CFI Flash has shared address and data bus. In SOPC builder there is Tri-State component using which I can share address and data bus. But now in Qsys there is four types of tri-state component.

Is any one try to use these tri-state component in Qsys ?

Please help on this.

Thanks,

Hardik Sheth

    You'll want this sort of connectivity:

    
    Generic tristate controller -->
                                    Tristate pin sharer --> Tristate bridge
    Generic tristate controller -->
    
    The Generic tristate controller has a bunch of presets for various things like SRAM, flash, etc... The pin sharer acts as an arbiter, and the tristate bridge just interfaces with the pins.
