Default toggle rates for unspecified signals
Default toggle rate used for input I/O signals
Allows you to specify a default toggle rate for the Power Analyzer to assume for all primary I/O signals, which include input I/O, bidirectional (input path), and virtual pins. You can specify the toggle rate as a percentage of clock cycles in which the signal toggles, or as a number of transitions per second, where a transition is defined as a change of state from 0 to 1 or from 1 to 0.
