有限状态机(Finite-State Machine,FSM),又成为有限状态自动机,简称状态机,是表示有限个状态以及在这些状态之间的转移和动作等行为的数学模型。笔者常在电机控制、通信协议解析等应用场景下应用FSM。 本文所讲的是基于硬件描述语言Verilog HDL的有限状态机的编写技巧及规范。众所周知FPGA以其并行性和可重构性为世人所知...
要清楚的知道RTL code经过综合之后会生成什么样的电路,那些电路符不符合预期,timing好不好处理,面积好不好优化。 状态机设计 •硬件电路会经常用到有限状态机(finite state machine,FSM)。 •状态机从大的分类上分两种Moore和Mealy。这两种的区别在于Moore状态机的输出只与当前状态有关;而mealy状态机的输出不...
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...
