Convert Xilinx Carry4 to Intel Carry

I have a project that uses the Xilinx carry4 primitive and I need to convert it for use in an intel board. What is the intel carry architecture? how can the carry4 be converted?

 

I am a university student trying to create a TDC and I am new to Quartus. Id appreciate any help.

 

Thanks!

Attached is the file. The issue is that Xilinx has a carry4 primitive while intels carry sum is 2 input. Thank you so much!

Hey, thank you so much. I'm new to VHDL so I'm afraid I have some basic questions. First work.vhd_prim doest seem to compile. Work does not contain primary unit vhd_prim comes up. Second, when those lines are removed I get an error saying carry4 is used but not declared. What changes did you implement? Thank you so much for you help.
