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...
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 ...

数字电路与VerilogHDL --时钟同步的状态机 4.1.1状态机的基本结构及类型 有限状态机的标准模型如图4.1.1所示,由三部分组成: 一是下一状态的逻辑电路, 二是存储状态机当前状态的时序逻辑电路, 三是输出组合逻辑电路。 4.1.1状态机的基本结构及类型 一般情况下,状态触发器的数量是有限的,其状态数也是有限的,故称...
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; VHDL Example: ...

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 ...
Here is an example of the expected inputs and outputs. The 'x' states may be slightly confusing to read. They indicate that the FSM should not care about that particular input signal in that cycle. For example, once the 1101 and delay[3:0] have been read, the circuit no longer looks...
