VERILOG(15) FINITE STATE MACHINES 应该是题目SIMPLE one-hot state transitions 3 FSM1 有限状态机(Finite State Machine, FSM)是一种用于描述系统行为的数学模型,它由一组有限状态和状态之间的转移规则组成。有限状态机在工程、计算机科学和数学中广泛应用,用来表示和分析具有离散状态的系统。 有限状态
A state machine is a sequential circuit that advances through a number of states. The examples provide the Verilog HDL codes to implement the following types of state machines.
User-Encoded State Machine This example uses the syn_encoding synthesis attribute value user to instruct the software to encode each state with the value defined in the Verilog HDL source code. By changing the values of the state constants, you can change the encoding of the state mac...
Here's example of my state machine coding in verilog: --- Quote Start --- always @(posedge clkADC or posedge RST) begin if (RST) state <= s0; else case (state) s0: if (START) state <= s1; else state <= s0; s1: ns <=s2; s2: ns <=s3; s3:...
SystemVerilog and Verilog has a unique (pun intended) and efficient coding style for coding one-hot state machines. This coding style uses what is called areverse case statementto test if a case item is true by using acaseheader of the formcase (1’b1). Example code is shown below: ...
state machine2 has the general structureshown in Figure 1.The current state of the machine is stored in thestate memory, a set of n flip-flops clocked by asingle clock signal (hence “synchronous” statemachine). The state vector (also current state, orjust state) is the value currently ...

Clearly, in a complex design it is difficult sometimes to do this without some formal approach, but it is often the case that some preliminary analysis can make a big difference in the efficiency of the final design. In this simple example, we have aninitial statewhere the machine has no ...
This will load in an example Verilog file which contains a state machine which has a design issue. Before the design is loaded and analyzed, click on the design settings to see how the FSM analysis for this example is configured. Loading the design will perform the FSM Analysis, and results...
软件设计中,FSM(Finite-State Machine)分为3部分:状态(State),事件(Event),动作(Action)。 状态模式(State Pattern)是行为型(Behavioral)设计模式,将软件主机端的行为归类为各个状态,状态之间可以互相转化,每种状态的行为不相同;统一交给一个Context类型的模块负责调度各个状态的跳转; ...
