a) 两段式状态机可以较清晰完整的显示出状态机的结构。 b) 可以轻易的将状态图state diagram转换为verilog code。 c) 代码清晰,降低编写维护复杂度。 回到顶部 3. 一段式状态机(不推荐) 上文中我们说道一段式状态机为一个always块,那么根据图1我们可以知道,一段式状态机要同时包含状态跳转和信号输出,即如图2...
This paper will also detail Accellera SystemVerilog enhancements that will facilitate and enhance future Verilog FSM designs. In this paper, multiple references are made to combinational always blocks and sequential always blocks. Combinational always blocks are always blocks that are used to code ...
As technology scales, the protection of Finite State Machines' (FSMs) states against single event upset and multiple bit upsets becomes more difficult. In this paper, a self-checking approach to enhance the SEU/MBUs immunity of FSMs' states by replicating One-Hot code times for s...
I am developing a fsm to latch on to incoming data and compute its average in verilog, but my fsm seems to be just stuck at one state. Although the simulation shows it did shifted perfectly in previous states, but it is stuck at "filter_data_64" state . See complete code below ...

SystemVerilog与Verilog描述状态机_FSM_之比较
Verilog FSM designs. In this paper, multiple references are made to combinational always blocks and sequential always blocks. Combinational always blocks are always blocks that are used to code combinational logic functionality and are strictly coded using blocking assignments (see Cummings[4]). A com...
