Making multiple nonblocking assignments to the same variable in the same always block is defined by the Verilog Standard. The last nonblocking assignment to the same variable wins! (See reference [5] for details). 6.2 10-state simple FSM design - one always blocks Example 5 is the fsm_cc7...
With the default_state set for the fsm_safe_state attribute, the value applied to the state register in the default or "when others" section of a case statement will be used as the safe state. Verilog Example: (* fsm_safe_state = "reset_state" *) reg [2:0] state; ...

The ASMD-FSMD technique for designing digital devices consists in building an algorithmic state machine with data-path (ASMD) describing the behavior of the device, and creating a project code in Verilog language in the form of a finite state machine with data-path (FSMD). The ASMD-FSMD ...
有四个状态的状态机需要2个flip-flops Each state has a unique state number, and states are usually assigned numbers as s0 (state 0), s1, s2, and s3 (for the four-state example). 每一个状态都有唯一的状态编号 As well as containing flip-flops to define the individual states of the FSM ...
