Hi ABely5,

Thank you for joining this Intel Community.

Based on the error message shown above, seems like the termination value is not comply with the I/O standard used.

You can find the supported OCT value and RZQ value based on the I/O standard applied from Cyclone V device handbook in I/O chapter "On-Chip I/O Termination in Cyclone V Devices" (page 143).

Hope this helps.

Thanks

Regards,
