i have problem when i try open ofdm_modulation_v72 when
i try to open have 3 part
using quartus prime edition 15 can't working which right way to open? ?
Can you try using the latest version of Quartus 19.1 ?
Also can you describe what exactly you are trying to do and where did you face issue?
I understand from your description you are trying to use an IP but face some issue while opening it (Are you able to generate IP files ? or You face an issue in Synthesis ? )
