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1 T的high pulse,timing diagram如上圖所示。 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...
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c...

We will be using the arbiter FSM to study FSM coding styles in Verilog. Verilog Code FSM code should have three sections: Encoding style. Combinational part. Sequential part. Encoding Style There are many encoding styles around, some of which are: Binary Encoding One Hot Encoding One Cold...
5. Two Always Block FSM Style (Good Style) One of the best Verilog coding styles is to code the FSM design using two always blocks, one for the sequential state register and one for the combinational next-state and combinational output logic. module fsm_cc4_2 (output reg gnt, input dly...
技术标签:verilog 有限状态机(Finite State Machine, FSM),根据状态机的输出是否与输入有关,可分为Moore型状态机和Mealy型状态机。Moore型状态机输出仅仅与现态有关和Mealy型状态机不仅与现态有关,也与输入有关,所以会受到输入的干扰,可能会产生毛刺(Glith)的现象,所以我们通常使用的是Moore型状态机。 状态机的编...

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...
See https://www.altera.com/en_us/pdfs/literature/hb/qts/qts-qps-handbook.pdf , section 2-12 for recommended HDL coding styles. The problem with writing always @(clk) Is that in simulation it will behave like a dual edge flop, but as synthesis treats it as always ...
one of the most common fsm coding styles in use today is the one sequential always block fsm coding style. this coding style is very similar to coding styles that were popularized by pld programming languages of the mid-1980s, such as abel. for most fsm designs, the one always block fsm...
