IBIS & modelling Hi-Z

How can I model a Hi-Z condition of my Cyclone I/O when using Altera's Cyclone IBIS model?

What you could do is to change the model_type parameter of a particular I/O model to 3-state.  

For example, to change the I/O model of 1c_ttl33_io_d12 to 3-state model you need to open the IBIS model in a suitable editor and change “I/O” under the Model_type keyword to “3-state”.
