What must correspond in a state machine that has a transition initiated by a signal event?

In a state machine with a transition that is initiated by a signal event, there is a critical aspect that needs to correspond effectively: the name of the signal event and its reception. This means that the state machine must be able to recognize and properly handle the received signal. When a signal event occurs, it triggers a transition from one state to another, and for this transition to be valid, the state machine needs to have a defined reception for that specific signal event.

The state machine relies on the naming of the signal event because the transition logic is tied to how the event is defined and captured. If the name of the signal event does not match what the machine is expecting, then the transition will not occur as intended. Thus, ensuring that the name of the signal event corresponds to how it is received is fundamental for the transition to function correctly within the state machine. This alignment is essential for the state machine to behave as designed when specific signals are encountered.

Understanding this correspondence helps ensure that the correct state transitions occur in response to events, which is vital for the expected operation of any system modeled with a state machine.
