Re: IBIS Model
Thanks for your interest in IBIS! To answer your question, IBIS today is *not* unsuitable for high-frequency simulation, depending on the level of IBIS you choose to use. IBIS 3.2 has been demonstrated to correlate well to SPICE transistor-level simulations at 1.25 GHz and beyond.
For high-speed differential interfaces, data-dependency issues and other concerns make the use of the IBIS 4.1 and 4.2 multi-lingual extensions more appropriate. Here you can combine an IBIS wrapper with Verilog-A, Verilog-AMS, VHDL-AMS or even Berkeley SPICE. In this way you can represent much more complicated behaviors than the traditional IBIS 3.2 I-V, V-t and C_comp will allow.
You can see examples of both traditional IBIS at multi-GHz rates plus the multi-lingual extensions in the IBIS Summit archive:
