Verilogcodingstyles Verilog coding styles 本文主要是收集一些重要的Verilog coding style。一个好的coding style可以减少错误的发生,增加电路的效能,以及较好的可读性。 Text The order of module signals 一个module signal顺序如下 (由左至右): Input clock signals(clk_*) set/reset signals(set_*, rst_*) ...
Finite state machine (FSM) is one of the first topics taught in any digital design course, yet coding one is not as easy as first meets the eye. There are Moore and Mealy state machines, encoded and one-hot state encoding, one or two or threealwaysblock coding styles. Recently I was ...
There are many ways to code these state machines, but before we get into the coding styles, let's first understand the basics a bit. There are two types of state machines: Mealy State Machine : Its output depends on current state and current inputs. In the above picture, the blue dotte...
1.状态变量编码(摘录自《Coding And Scripting Techniques For FSM Designs WithSynthesis-Optimized, Glitch-Free Outputs》)。注:此方法仅对输出为一位,即输出用高低电平表示时有效。 a.确定状态机中输出(outputs)个数x和状态(state)个数y,并制作一个(y+1)*(x+1)的表格,根据实际的每个状态的输出填表。查找...
Another 40+ slides help to demonstrate multiple efficient Finite State Machine (FSM) coding styles. An EISA bus arbiter lab is designed to reinforce FSM concepts developed in class (no silly traffic-light controllers or soda pop change machines in this course!) ...
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 ...

•在RTL coding时最重要的一点是,要清楚的知道你写的代码是硬件电路的描述,不是高级语言的功能仿真。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...
