DIVA simulation

Dear all,
I am looking to obtain analysis for visual and thermal comfort for my model.
I have tried Honebee plus for daylight and Honeybee for comfort and energy consumption analysis.
However, I have seen DIVA can analyze both at the same time.
My questions are,
What engines is DIVA using for visual and comfort analysis and what is the benefit of using DIVA?

Is It accurate and validated as the same as other results with Honeybee and Honeybee plus?

Thanks in advance
