paper:synthesizable finite state machine design techniques using the new systemverilog 3.0 enhancements 之 standard verilog FSM conding styles(三段式)

Three always block style with registered outputs(Good style)…

paper:synthesizable finite state machine design techniques using the new systemverilog 3.0 enhancements 之 standard verilog FSM conding styles(二段式)

1.Two always block style with combinational outputs(Good Style) 对应的代码如下: 2段式总结: (1)the combinational always block sensitivity list is sensitve to changes on the state variable and all of the inputs referenced in the combinaltional always block. 这个实际中…

paper:synthesizable finite state machine design techniques using the new systemverilog 3.0 enhancements 之 FSM Coding Goals

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 4.the coding style should yield effi…

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.…

paper:synthesizable finit state machine design techniques using the new systemverilog 3.0 enhancements之fsm summary

主要是1.不要用1段式写FSM 2.不要用状态编码写one-hot FSM ,要用索引编码写one-hot FSM.…

paper:synthesizable finit state machine design techniques using the new systemverilog 3.0 enhancements之全0/1/z/x的SV写法

…

paper:synthesizable finit state machine design techniques using the new systemverilog 3.0 enhancements之enhanced coding styles

1.ANSI style 的代码比较紧凑. 下面规范推荐,比较好. 下面是带有parameter的module header的完整规范 一般1bit ,大家都是wire signal1 = gen_signal1_logic; 这种写法.似乎也不是直接assign signal1=gen_signal1_logic,不声明wire signals;. 个人一般就用always@(*),觉得带个()这样1.易于跟seq的统一2.易于看到*.…

paper:synthesizable finit state machine design techniques using the new systemverilog 3.0 enhancements之fsm1各种style的timing/area比较

整体说,一般还是用2段式,再加上output encodecd/default -X技巧.…

paper:synthesizable finit state machine design techniques using the new systemverilog 3.0 enhancements之output encoded style with registered outputs(Good style)

把输出跟状态编码结合起来,即使可以省面积又是寄存器输出.但是没有讲解如何实现这种高效的编码.…

paper:synthesizable finit state machine design techniques using the new systemverilog 3.0 enhancements之onehot coding styles(encoded-parameter style with registered outputs不推荐但是经常有人写这样的代码)

这样写法,不利与综合,case语句中比较也是full-vector比较.…
