Due to a problem in the auto-generated High-Definition Multimedia Interface (HDMI) IP Core sdc file, you may see the following warning during compilation when the IP is configured in TX mode:
Warning (332174): Ignored filter at <auto generated filename>.sdc(102): *bitec_hdmi_rx*|delayed_wrptr_g could not be matched with a register
This problem occurs because both the RX and TX timing constraints are applied to the auto-generated sdc file regardless of the mode of the IP.
When operating in TX mode, this warning can be safely ignored.
This problem is scheduled to be resolved in a future release of the Intel® Quartus® Prime Pro Edition Software.
