- main page: state transition table.
A state table defines all details of the behaviour of a state of a VFSM. It consists of three columns: in the first column state names are used, in the second the virtual conditions built out of input names using the positive logic algebra are placed and in the third column the output names appear:
| State Name | Condition(s) | Actions(s) |
|---|---|---|
| Current state | Entry action | Output name(s) |
| Exit action | Output name(s) | |
| Virtual condition | Output name(s) | |
| ... | ... | |
| Next state name | Virtual condition | Output name(s) |
| Next state name | Virtual condition | Output name(s) |
| ... | ... | ... |
Read the table as following: the first two lines define the entry and exit actions of the current state. The following lines which do not provide the next state represent the input actions. Finally the lines providing the next state represent the state transition conditions and transition actions. All fields are optional. A pure combinatorial VFSM is possible in case only where input actions are used, but no state transitions are defined. The transition action can be replaced by the proper use of other actions.

Famous quotes containing the words state and/or table:
“[17th-century] Puritans were the first modern parents. Like many of us, they looked on their treatment of children as a test of their own self-control. Their goal was not to simply to ensure the child’s duty to the family, but to help him or her make personal, individual commitments. They were the first authors to state that children must obey God rather than parents, in case of a clear conflict.”
—C. John Sommerville (20th century)
“When I think of our lands I think of the house
And the table that holds a platter of pears,
Vermilion smeared over green, arranged for show.”
—Wallace Stevens (1879–1955)
