Set/Reset to out paths are not always critical paths, and in the majority of designs they will not be critical. We are expected to be turning this analysis off by default in a later release. Currently, you will see this analysis performed by default.
To prevent this analysis, uncheck the reg_sr_o in the Path Tracing Control options. This will prevent the Set/Reset to out analysis from being performed.
This analysis is used to check clock to out times, and it is important for a design that requires Set/Reset values to propagate to a downstream device in a specified amount of time.
