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...
将之前的例子用Mealy FSM重新改写,原本在Moore FSM下,若input w_i为连续2个clk为high,则output会在下1个clk产生周期为1 T的high pulse,若改用Mealy FSM,则output会提早1个clk出现,如下图所示。 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。

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...
Design and implementation of MAC Transmitter for the transmission of UDP packet using FSM and verilog coding techniquesThe purpose of this paper is to design and develop a MAC Transmitter on Field Programmable Gate Arrays (FPGA) that converts 32 bit data in to 4 bit DATA for transmitter. The...
In Verilog, there are three primary coding styles: Behavioral Coding: This style focuses on describing the system’s behavior without detailing its structure. It primarily uses constructs like always blocks and procedural assignments to model functionality, making it easier to conceptualize complex operat...
