Avalon Bus Address alignment

Hi, I want to know how to use the Avalon Bus Address alignment feature. Is it automated by the Nios to choose the address alignment or do we have to manually do it ?

Without byte enable the slave port uses native address alignment and following formula is used to calculate the address:

master address = slave base address + (slave word offset * master data width in bytes)
