Xilinx Blocks
A block diagram of this type of state machine is shown below:
Figure 3-80: Moore State Machine block diagram
The block is configured by providing a next state matrix and an output array. They are defined by the state machine’s next state/output table. For example, consider the problem of designing a state machine to recognize the pattern ’1011’ within a serial stream of bits. The state transition diagram and equivalent transition table are shown below.

The table lists the next state and output that result from the current state and input. For example, if the current state is 4, the output is 1, indicating the detection of the desired sequence, and if the input is 1, the next state is state 1.
