7–54 Chapter 7: Power Estimation Assignments
POWER_TOGGLE_RATE
POWER_TOGGLE_RATE
Type
Specifies the toggle rate assumed by power estimation for the signals generated by
this node or entity. The units for this value are transitions per second and the value
must be positive. The value provided should be the expected time-averaged toggle
rate, rather than worst case (highest possible) toggle rate. A different assignment,
Toggle Rate, applies to I/O pins only and is used by the Fitter and by I/O
Assignment Analysis to verify signal integrity under worst case conditions (highest
possible toggle rate). Use the Synchronizer Toggle Rate if you want to configure the
data rates used for Metastability Reporting in the TimeQuest timing analyzer.
