lvds_rule_tx_serial_width (error)
Message Unsupported serializaion width: 9
To fix The LVDS block does not support a serialization wiudth of 9. Choose another width.
lvds_rule_tx_vref (error)
Message This resource is reserved as vref for bank <name>. Us a different resource to configure LVDS
Tx custom output differential type
To fix Some resources can be used as the VREF for an I/O standard. If you are using an I/O standard
that uses a VREF pin, you must use this resource as a VREF. Choose another resource for the
LVDS function.
Message GPIO <name> has to be configured as vref input mode to support LVDS Tx custom output
differential type
GPIO <name> has to be configured as vref input to support LVDS Tx custom output
differential type
To fix If you are using an I/O standard that uses a VREF pin, you must use this resource as a VREF.
Configure the GPIO as an input and choose vref as the Connection Type.
Message LVDS Tx custom output differential type cannot be used due to unbonded vref resource on
the same bank <bank>
LVDS Tx custom output differential type cannot be used due to vref resource not bonded out
To fix If a VREF pin is not available in the I/O bank (e.g., it is not in the FPGA/package you chose),
you cannot use an I/O standard that requires it. Instead choose a different I/O standard or a
different resource.
