11 years agoThanks a lot for your reply. I now understand that unconstrained paths are not an issue here. Also, the altera_reserved_clk did not have problem.
I was able to create .sdc file and my circuit is working correctly now along with switches, LED and LCD as well. Just one quick question, I followed the steps correctly but I did not use .BDF file while I got the output. When I have .vhd file as my top entity where I instantiate my processor then the circuit works correctly, whereas I get ".ELF download fail" error if I use .bdf as my top level entity. Could you please tell me why that happens? Thank you.
