AM1808 IBIS model

Other Parts Discussed in Thread: AM1808

My customer needs help running an IBIS simulation with a 3.3V output - see below:

I’ve downloaded the AM1808 IBIS Model and have gotten it to run in simulations in Hyperlinx, but the only output I can get from it is 1.8V.  I would like to simulate a 3.3V signal.  The IBIS Model seems very complex, but I think there is a simple way to select a 3.3 V Output.

    Ignacio,

       If you look into the current IBIS model source, you'll see some [Model Selector] Values for the Corresponding Buffers. You'll need to use the [Pin] Keyword to determine which Model to associated with a 3.3V Input.
