iMx6UL supply voltage dip

In our design, we have voltage monitoring with watchdog(max16002) for processor voltages(5V, 3.3V, VDDARM, VDDR1V5), this voltages are generated by LDOs.  In voltage monitoring watchdog any voltage dip means watchdog has to trigger. 

is their any way in processor that voltage level can be made dip so that watchdog can be tested?.

one way is hardware voltage injecting to input of voltage monitoring ICs but we are looking in software level that in processor can be loaded so that voltages levels are dip.
