Hello Sanjay,


Thank you for reaching out Intel FPGA Community.


Please find below the:


CAUSE: The source I/O pin driving the I/O input buffer must only drive the I/O input buffer primitive and nothing else, however it also drives to other destinations. The specified I/O input buffer primitive is illegally configured.

Regards,

Aqid
