Can LVGL be used for safety critical system

General discussion
1

We are developing a product which will be used in automotive industry.
Can i use LVGL for displaying graphics in the product we are developing, as i saw some GUI framework being certified for SIL ( Safety Integrity Level ) which ensures fail safe operation.
Any pointers helps me in deciding to go ahead with LVGL usage.
Thanks In Advance

Welcome and why not. But choice one stable version and check . LVGL is only simple memory gui and safety level is based on safety display and indev drivers and callbacks, that isnt part of LVGL.

Personally I would try to “decouple” the safety part and the visualization part. So, even if the visualization were to crash, the safety should keep on running.
So an E-stop as part of the visualization, although possible, I would recommend you move that to one of those nice big buttons.But the feedback on the current status of the safety, sure, why not.
