Hi Matthew, 

     I am not user of HyperLinx, but I am interesed to know how HyperLinx 
simulates IBIS models, in special how Hyperlinx simulates different types of 
buffers by means of IBIS models. Is it possible that there are differencies 
in the accuracy of IBIS simulations between HSPICE and Hyperlinx?  With this 
information I can consider to use HyperLinx. 

                  Regards,
