LogiCORE IP DisplayPort v4.2 - Why do I receive a Critical Warning saying the Reed-Solomon Decoder license is not found, and an Error in Synthesis saying a license was not found when the DisplayPort core is configured as a DisplayPort Sink?

Description

Why do I receive a Critical Warning saying the Reed-Solomon Decoder license is not found, and an Error in Synthesis saying a license was not found when the DisplayPort core is configured as a DisplayPort Sink?

Critical Warning:  [IP_Flow 19-651] IP license key 'rs_decoder@2013.03' is unlicensed.


Error: WARNING: [Synth 8-3848] Net mark_in in module/entity rs_decoder_axi_wrapper__parameterized0 does not have driver. [c:/project_1/project_1.srcs/sources_1/ipshared/xilinx.com/rs_decoder_v9_0/ec854a9b/hdl/rs_decoder_axi_wrapper.vhd:805]
INFO: [Synth 8-256] done synthesizing module 'rs_decoder_axi_wrapper__parameterized0' (142#1) [c:/project_1/project_1.srcs/sources_1/ipshared/xilinx.com/rs_decoder_v9_0/ec854a9b/hdl/rs_decoder_axi_wrapper.vhd:547]
Fatal Error. License Check failed for secure IP. Exiting Synthesis.

Solution

When configured as a DisplayPort Sink the DisplayPort core uses the Reed-Solomon Decoder as part of the Audio feature.  

If Audio is enabled a Reed-Solomon Decoder license will be required in addition to the DisplayPort license.

More information on the licensing options for the DisplayPort core can be found in the LogiCORE IP DisplayPort Product Guide PG064 under Licensing and Ordering Information section, or on the LogiCORE DisplayPort product page.

There is also a known issue in the DisplayPort v4.2 that causes the core to look for a Reed-Solomon Decoder license, and throw a Critical Warning, even when the Audio feature is not being used.

This message can be safely ignored if the Audio option is not being used.
