Hi Sir,

Thank you for joining this Intel Community.

May I know which Quartus version are you using? Can you provide the design for debugging purpose?

Thanks

Hello, Quartus version is 18.1.1 running on Linux. I cannot provide the design. Thanks, Dave 781-863-4694 LEX 2 Forbes Rd, Lexington MA 02421
