A:T触发器(Toggle Flip-Flop)只有一个信号输入端,在时钟有效边沿到来时,输入有效信号则触发器翻转,否则触发器保持不变,因此T触发器能够实现有效的计数功能。4个T触发器可以构成4位同步计数器,当Enable信号为高电平时,计数器会在时钟信号的上升沿递增,当Clear信号为低电平时,计数器将会在下一个时钟上升沿复位。 T...

Verilog | T Flip Flop with What is Verilog, Lexical Tokens, ASIC Design Flow, Chip Abstraction Layers, Verilog Data Types, Verilog Module, RTL Verilog, Arrays, Port etc.
Verilog creates a level of abstraction that helps hide away the details of its implementation and technology. For example, a D flip-flop design would require the knowledge of how the transistors need to be arranged to achieve a positive-edge triggered FF and what the rise, fall, and CLK-Q...
//***code***// endmodule T触发器概念 T触发器(Toggle Flip-Flop,or Trigger Flip-Flop)只有一个信号输入端T,在时钟有效边沿(上升沿/下降沿)到来时,T端输入有效信号,则触发器翻转,否则触发器保持不变。触发器的输出信号有一个,当T端为0时,输出取Q,当T端为1时,取Q的反相Q_bar。 T触发器特征方程...

It can also be used later as a first validation method of the triplicated code. The script checks whether the output of a flipflop is connected to a voting cell. If this is the case, then it will be placed in the triplicated.txt file. Otherwise it is placed in not_triplicated.txt....
Flip-flops (or more briefly “flops”) will be used as an example of a memory element in the description below. However, any memory element may be used in other embodiments, and any combination of memory elements may be used where there is more than one memory element. Memory elements may...

You should never try to model a flip flop with NAND gates in Verilog. You should always use the appropriate level of abstraction for a flip flop: behavioral modelling. This avoids all the issues that you are encountering, especially simulation race conditions. In addition to...
