Hey Vishnu

As you may know, Amrita does not release any cutoff marks or ranks as such and everything is a speculation. Also it highly depends on yoyr category and domicile. Amrita follows first come first serve basis in counselling so you nneed to take that into account to but on a general level any rank below 2500 can get you a seat in CSE in Coimbatore or Bengaluru campus(based on previous year counselling records). If you have a domicile certificate of the Tamil Nadu (for coimbatore campus) or Karnataka(for bangalore campus) then you can get a seat with even 6000 rank.
