State Machine Example
The figure below shows a simple 2-state FSM. This can be easily extended to more states. Notice that a variable
called “state” is declared to be persistent and is initialized to 2 bits, unsigned using the “xl_state” function. A
switch-case statement is then used to decode the inputs, branch to the next state and assign the outputs.
