Are you changing the termination voltage along with the operating voltage?

According to the data sheet, the product can work under 2 different voltage range, let say 2.60V and 3.30V. But, when I modeling this product, I found that only 1 of them pass the IBIS checker (for 3.30V) . The other 1 (2.60V) fail with errors on Falling/Rising Waveform. The schematic and control file I use is the same. I just use 2different references voltages. Can I conclude that the product just can work under the voltage range that pass the IBIS checker ?
