Yet another approach to write the VHDL code for the state machine is to create a structural model. The structural model describes all actual gates and flip-flops and their connectivity. An example of this is shown in Fig. 2-58, page 108, in the textbook. Finally, there is yet another way of describing a state machine: state machine editor. Jul 05, 2017 Moore State Machine. The Output of the State machine depends only on present state. The output of state machine are only updated at the clock edge. Let’s construct the sequence detector for the sequence 101 using both mealy state machine and moore state machine. Moore state require to four states st0,st1,st2,st3 to detect the 101 sequence.

This page consists of design examples for state machines in VHDL. A state machine is a sequential circuit that advances through a number of states. The examples provide the HDL codes to implement the following types of state machines:
- 4-State Mealy State Machine
The outputs of a Mealy state machine depend on both the inputs and the current state. When the inputs change, the outputs are updated without waiting for a clock edge.

- 4-State Moore State Machine
The outputs of a Moore state machine depend only on the present state. The outputs are written only when the state changes (on the clock edge).
- Safe State Machine
This example uses the syn_encoding synthesis attribute value safe to specify that the software should insert extra logic to detect an illegal state and force the state machine's transition to the reset state.
- User-Encoded State Machine
This example uses the syn_encoding synthesis attribute to apply specific binary encodings to the elements of an enumerated type.
