High Speed Differential I/O is the dedicated I/O standard for the transmitter in Arria 10 transceivers.
The Quartus Prime software automatically selects the appropriate slew rate depending on the configured data rate or functional mode.
In QPI mode, if VCM < 0.17 V, the input Vid must be greater than 100 mV. If VCM > 0.17 V, the input Vid must be greater than 70 mV.
