High-z state
Web1 Logic one, “high” Z or ? High impedance (tri-state buses) X Unknown value (simulation) “X” is used by simulators when a wire hasn’t been initialized to a known value or when the predicted value is an illegitimate logic value (e.g., due to contention on a tri-state bus). Verilog also has the notion of “drive strength” but we can ... WebA tri-state output can either drive the output line high, drive it low, or enter "hi-Z state" (a.k.a., "high impedance state", a.k.a., "disabled", a.k.a., "tri-stated"). In high-Z state, the output pin …

For a variable with a 4-state data data type, X is the default initial state, meaning its value is unknown and has the potential to be any value. This is a symbolic state as real hardware will be in a particular state 0 or 1 at any specific point …
WebSep 29, 2024 · A three-state logic level, has three outputs. These outputs are as follow: 1, 0 , and “Hi-Z,” or “open.” The hi-Z state is a high-impedance state in which the output is … WebWhen the switch is high impedance (an input), the a little bit of the power supply goes through the resistor and holds the pin high. This defines the high state (1), and we can say the pin is 'pulled high'. Instead of being a random 1 or 0 when we read it, it will always be 1.
