1. We cannot guarantee the model. The data can be used only for the reference.
2. In the IBIS specification, a termination resistance value have to be 50 ohm.
   But, it it not possible to specify dV/dt value to 50 ohm load for a CMOS output cells.
   So, we used 5 Kohm as a termination resistance. This is a standard method for a CMOS IC.
