Clock Frequency Summary

The Clock Frequency Summary consists of the following data.

The User target constrained clocks table lists the user constrained clocks; that is, the clocks you defined with the create_clock and create_generated_clock constraints in your SDC file. The clock target is the specific pin or port in the core timing netlist.
The Maximum possible analyzed clocks frequency table shows the maximum clock frequency that each clock can achieve using the critical paths.
The geomean is the geometric mean of the clock periods.

Note: This Clock Frequency Summary only shows the setup result. However, later, the report shows the most critical hold paths (you need to scroll down to after the detailed most critical setup path section).
