running aging simulation with different bias voltage and temp over time

Hi,

Is it possible to run aging simulation for two pattern, say we we want to run aging sim for 10 years, for first 5 years VDD=1.8V & temp=30 and next 5 years it should be VDD=3V and temp=45.

I explored "rxprofile" options but couldn't found a way to do it.

Thanks,

Nasser
