因此設計了Moore FSM,state diagram如上圖所示,接下來要做的就是用各種coding style來實現這個Moore FSM。 1.使用3個always (三段式) simple_fsm_moore_3_always_best.v / Verilog 1/* 2(C) OOMusou 2011http://oomusou.cnblogs.com 3 4Filename : simple_fsm_moore_3_always_best.v 5Synthesizer : Q...
所以可以發現,整個Moore FSM事實上是由2塊的組合邏輯與1塊D-FF所構成,我們常聽到所謂的一段式、二段式與三段式FSM,事實上就是由這3個block排列組合而成。 Moore FSM各種coding style比較 為了要實際比較各種coding style,在此舉一個簡單的例子,若input w_i為連續2個clk為high,則output會在下1個clk產生周期為...

Please refer to tidbits section for "writing FSM in Verilog". How do I avoid Latch in Verilog ? Latches are always bad (I don't like that statement); latches are caused when all the possible cases of assignment to variable are not covered. Well this rule applies to combinational blocks...

原本Moore FSM需要3个state,若改用Mealy FSM后,会只剩下2个state,接下来要用各种coding style来实现Mealy FSM。 1.使用3个always (三段式) simple_fsm_mealy_3_always_best.v / Verilog 之前提到使用Mealy FSM会少Moore FSM 1个state,且output会早Moore FSM 1个clk,所以最后特别将output在敲一级delay 1个...
1.the fsm coding style should be easily modifiable to change state encoding and FSM styles. FSM 的的 状态编码和风格易于改变 2.the coding style should be compact. 代码比较紧凑 3.the coding style should facilitate debugging. 代码易于debug ...
