From a state machine perspective, this is fairly simple as shown in this diagram. The reset state (thick blue line) assumes there are no one bits, or an even number, so the output is a 1 (so that ...

A state machine consists of a set of states and a case selector that determines which state the program transitions to next. See Figure 1. Figure 1: Block diagram of a typical digital-controlled dc–dc ...

State Diagrams A nice aspect of the state machine concept is its compelling graphical representation in the form of state diagrams.

FSM Coverage enables users to determine which states and transitions in the state machine diagram have been executed during simulation.

IAR Systems’ Visual State, which works on Linux and Windows, simplifies the task of creating state-machine models.
