Critical Issue
The Arria V design example for MST in the DisplayPort IP core fails compilation.
This issue is caused by the txN_vid_f pins that still appear in the
design example top level file (mst_av_sk_4k.v) even though the pins
were removed from the DisplayPort IP core version 15.1.
To work around this issue, remove the txN_vid_f pins from the
mst_av_sk_4k.v file and recompile the design example.
This issue will be fixed in version 15.1 Update 1 of the DisplayPort IP core.
