Document Table of Contents Static Probability

The static probability of a signal is the fraction of time that the signal is logic 1 during device operation. Static probability ranges from 0 (always at ground) to 1 (always at logic-high).

The static probability of input signals impacts the design's static power consumption, due to state-dependent leakage in routing and logic. This effect becomes more important for smaller geometries. In output I/O standards that drive termination resistors, the static power also depends on the static probability on I/O pins.
