LT8620 stability using LT Power CAD

Hi All,

We are using LT8620 to generate 1.2V from 7.5V. We have very wide output load variation from 10mA load to 2A load. So, I would like to understand stability of the circuit that we designed under different loading conditions. Unfortunately, LT8620 is not supported in LT Power CAD. Is there an alternate device model which could be used to check stability. LT8610 datasheet seems very similar to LT8620. Can I use LT8610 to do stability plots? If not, is there any equivalent part which could be used to check stability in LTpower CAD? 

Thanks
