A state machine is a sequential circuit that advances through a number of states. By default, the Quartus II software automatically infers state machines in your Verilog HDL code by finding variables whose functionality can be replaced by a state machine without changing the simulated behavior of ...

Build a finite-state machine that searches for the sequence 1101 in an input bit stream. When the sequence is found, it should set start_shifting to 1, forever, until reset. Getting stuck in the final state is intended to model going to other states in a bigger FSM that is not yet im...
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...
