MODELS INCLUDED IN THIS TOOLKIT 
-------------------------------
There are 2 models included in this toolkit. They are the RX Continuous Time Filter (CTF) and is named 
IBIS_AMI_RX.dll and a simple Gain filter named IBIS_AMI_CHGAIN.dll.

INTRODUCTION
------------
The RX model does not have clock recovery and has fixed coefficients. The INIT function in
the model does not modify the impulse response. A waveform passed to the GetWave call will
undergo equalization.

In summary,
-The model does not modify the impulse response in the init call.
-It does not write a clk output.
-Tested for 5.0 GBPS data rate.

The CHGAIN filter is a simple model that simply multiplies the input wave by the gain factor (default is 2).
MODIFYING THE MODELS
--------------------
A very basic method of modifying the model is to vary the parameters that the model accepts.
The parameters of the IBIS_AMI_RX.dll is stored in the .ami file IBIS_AMI_RX.ami .
The parameters of the IBIS_AMI_CHGAIN.dll is stored in the .ami file IBIS_AMI_CHGAIN.ami .

Advanced users can add or modify a function in the INIT or GetWave functions to alter the
behavior of the model.
