    assign model to idle die in a stack die(multiple die) package

    xli

      Hi,

       

      I have a question about how to assign model to these idle dies  inside stack-die DDR or NAND package.

       

      In ebd model, one die is active as “ output” driver, how should we assign IBIS model to other idle dies?

       

      There are  “ buffer settings” as input, output, stuck high, stuck low.  I don’t think either works close to real case for these idle dies. Should we have a 3-state selection in IBIS model?

       

      Thanks
