8 bit Calculator VHDL with 4×4 Keyboard

I need a project made with the software Quartus.

My board is using an Altera chip, model: EP4CE6E22C8N.

I need a 8 bit calculator, that uses a matrix 4×4 keyboard and display the results in the 7 seegments display that my board has.

Board model: RZ-easyfpga a2.2

I attached on the job the pin diagram of my board.
