Kee Chai,
To create and IBIS model file you need all the relevent V/I and V/T data points, a valid pinlist file, master Pin file, RLC file. Also make sure that you have the timin-process loads (Vmeas, Vref, Rref and Cref) for all I/O,
Output, 3-state buffers.
In order to create the pin-list section of the ibis file, you will need to extract the [Pim], signal_name, model_name, R_pin, L_pin and C_pin from the master-pin, pin-list and RLC files. This you can do using MS-Excel,
Star-Office or you if you are prficient in a scripting langauge you can create script to do this.
I hope this helps
