When trying to target specific parts, there is a timing failure in the bitslice internal to the MIPI D-PHY IP when setting the line rate to 2500Mbps.
When the line rate is reduced to 2400Mbps this failure is no longer present.
This issue is due to incorrect reporting on the Vivado tool and can safely be ignored.
For users who cannot ignore this timing failure, please upgrade to a newer tool version or reduce the line rate to 2400Mbps.
This is a known issue and has been resolved in 2019.2.2 and later versions of the tools.
