Description
IEEE 1149.6 JTAG testing for transceiver I/O pins will fail if the device is not configured.
Resolution
Prior to attempting to perform IEEE 1149.6 JTAG testing on transciever pins, you must first configure the device with a valid bitstream. JTAG boundary scan support for transceivers must use post-configuration BSDL files.
This applies to Altera® transceiver capable devices supporting IEEE 1149.6 BSDL Files.
