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 ...
paper:synthesizable finit state machine design techniques using the new systemverilog 3.0 enhancements之onehot coding styles(index-parameter style with registered outputs) case语句中,对于state/next 矢量仅仅做了1-bit比较。 parameter 值不是表示FSM的状态编码,而是表示state/next变量的索引。
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...
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...
