Testing VOH, VOL, VIH, VIL
You fundamentally misunderstand the data-sheet. 

These numbers are guaranteed Max/Min values and you use them as part of your design.  If you are driving into the SOC then you must make those levels, if you are receiving the signal then you must be able to handle the at the very Most/Least those levels.

If these values are being exceeded the device won't make it out of the foundry.
