2016.3 licensing - IP license for 25G_FEC is not recognized in core generation

Description

I am seeing the following warnings in Vivado 2016.3.

The below command does generate the output products I require, but with the INFO messages and critical warnings below:

generate_target all [get_files c:/p5_16C_f/port_framework/ip/ieee802d3_25g_rs_fec_1/ieee802d3_25g_rs_fec_1.xci]
INFO: [IP_Flow 19-1686] Generating 'Synthesis' target for IP 'ieee802d3_25g_rs_fec_1'...
CRITICAL WARNING: [IP_Flow 19-651] IP license key 'ieee802d3_25g_rs_fec_only@2016.04' is unlicensed.

I have a purchased license for *ieee802d3_25g_rs_fec_full*.

However the critical warning is referring to *ieee802d3_25g_rs_fec_only*.

Can the above Critical Warnings be safely ignored or do I also need to have a separate license that contains this 'ieee802d3_25g_rs_fec_only" licensing feature?

Solution

"ieee802d3_25g_rs_fec_only" is for Transcode Bypass Mode. It is used for accessing the encoder and decoder without the transcoding.

The critical warnings are benign and can be safely ignored.
