LogiCORE Video PHY Controller v2.0 - Why does the Video PHY Controller throw error "ERROR: [Ipptcl 7-5] XIT evaluation error: File already exists:" when selecting HDMI TX/RX only configuration?

Description

Why does the Video PHY Controller in Vivado 2015.4 return the following errors and fail to generate when a HDMI Transmitter (TX) or HDMI Receiver (RX) only configuration is selected?

INFO: [IP_Flow 19-1686] Generating 'Synthesis' target for IP 'hdmirxcore_vid_phy_controller_0_0'...

ERROR: [Ipptcl 7-5] XIT evaluation error: File already exists: c:/test_project/test_project.srcs/sources_1/bd/hdmirxcore/ip/hdmirxcore_vid_phy_controller_0_0/synth/vid_phy_controller_v2_0_0.v

ERROR: [Common 17-39] 'xit::add_ipfile' failed due to earlier errors.

Solution

The Video PHY Controller v2.0 does not support generation of an HDMI TX or HDMI RX only configuration.

It should issue a warning to the user, but fails to do so. This will be resolved in the next release of the Video PHY Controller.

In Vivado 2016.1 and later, the feature to support generation of an HDMI TX or HDMI RX only configuration will be supported. For now, if you have an HDMI TX or HDMI RX only configuration, you will need to manually tie off the unused pins.

Please see (Xilinx Answer 66520) for a patch that changes the error to a proper warning that generating a HDMI TX or HDMI RX only configuration is not supported in Vivado 2015.4.
