Radiant: How does the user interpret the Single Clock Domain table entries on the Clock Summary section of the Place & Route Timing Analysis Report?
The Single Clock Domain table of the Clock Summary Section of the Place & Route Timing Analysis report:

There are three values on this table:
1. The
Target is the frequency or period based on the clock constraint. This should always be the lowest of the three frequencies (lower than the actual and lower than the maximum for the block) or at least equal to the actual frequency.
2. The
Actual is the actual frequency that the design can reach for the specific clock considering the timing delays due to logic. This could either be equal to the maximum clock frequency or lower but this should always be greater than the clock frequency set on the constraints.
3. The MPW is the maximum frequency that the specific clock can reach. This is either based on IO port standards if the clock is from a port, from fabric speed if the clock is generated from fabric, or if this is a clock from hardened blocks then this is limited by the physical implementation of the hardened block. MPW stands for minimum pulse width.
