I want to know which type of fpga I am using(ex: GT,Extended features or Base..)

Remove the F from the end and you have the part number. That tells you everything there is to know about the FPGA.

For a part number decoder (tells you all features of your device), see page 27 of the manual: https://www.altera.com/en_us/pdfs/literature/hb/cyclone-v/cv_5v1.pdf
