The state table is a description of the terminal behavior of a clocked synchronous sequential network. State Table/Diagram Specification There is no algorithmic way to construct the state table from a word description of the circuit. The second form of State Table has less number of rows than First Form of State Table and it is easier to fill. As shown in figure, there are two parts present in Moore state machine. State table/state diagram is constructed from word specifications. 6. Decide on the number of state variables. In generating a state table/diagram from a verbal description, can get more states than required. • Determine the number of states in the state diagram. Title: Microsoft PowerPoint - elec2200-11.ppt Author: STROUCE Created Date: 7. 0000022205 00000 n 2. At the start of a design the total number of states required are determined. A node represents a unique state of the FSM and it has a unique symbolic name. The LEDs used are current limited using 220Ohm resistor.

Derive a state diagram. 5. 0000055300 00000 n In state machine diagrams, you can describe the behavior of an object by adding states to a region of a state machine, composite state, or orthogonal state. The State Diagram • We will use the state diagram to specify the sequencing / timing behavior of objects in a class - States - Events - Transitions • Generally speaking, there should be one state diagram for every class - But this is not prescribed by UML, it allows state diagrams to describe the system at any level Choose the type of flip-flops to be used. Also, each flip-flop can move from one state to another, or it can re-enter the same state. Finding the right table design and elements in PowerPoint If you experience problems with creating excellent PowerPoint presentation design, we can help you. 3. The next step in our journey toward designing the logic for this system is to take the information we have in the state diagram and turn it into a truth table. Ex: starting from state 00!
