TIMING-47#1 Warning
|
|
False path or asynchronous clock group between synchronous clocks
|
|
A Clock Group timing constraint is set between synchronous clocks cpu_clk and sys_clk (see constraint position 6 in the Timing Constraint window in Vivado IDE). It is not recommended to cover synchronous clock domains with constraints that prevent timing analysis as the design could fail in hardware.

Scoped Clock constraint overwritten with the same name

A new clock constraint create_clock overrides a previous scoped clock constraint with the same name. It is not recommended to override a scoped (typically an IP) clock constraint and could result in unexpected behaviors.
