    Hi Shainy,


    You're using the wrong IP. You should be using ALTERA_MULT_ADD, you can refer to this document: https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ug/ug_lpm_alt_mfug.pdf#page=36


    Prior to Quartus II v14.0, these IP cores were called Megafunctions and used MegaWizard Plug-In to be generated into the design. Starting from Quartus II v14.0, they're referred to as IP, and you are required to use IP catalog to generate them. Although it's been a long time since Quartus v14.0, for Cyclone V devices, the MegaWizard Plug-In will be prompted to select the parameters after you have selected the Arithmatic IP core on IP catalog.
