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.
