Technology Models vs. full IBIS models

Dear friends,

We are evaluating a tool regarding signal integrity.
Our design is composed of modern devices ( DSP,DRAM,SRAM,FLASH,FCT etc).
Since we don't have the IBIS model for most of the parts, the supplier suggested that I use technology models. I have a DSP, so I assigned it as FCT, for it was the closest choise.
The PCB crosstalk simulation showed problems we NEVER faced with five practical PCBs.
I assume that I have to get/order/develop IBIS models for all the parts, and not
use "technology models".
Is that true ?
Has anyone went through these ?
Has anyone a benchmark, comparing the major tools , offered this field of signal integrity (crosstalk...).
