如何用 tikz 重现这个逻辑电路？

我不知道如何重现这个逻辑电路（见最后的图片）。我知道我可以使用 circuitikz 包，但很难正确对齐所有内容。

有人能幫助我嗎？

多谢。

答案1

首先，你几乎对所有东西都使用了错误的名称（RTFM）。其次，逻辑门只有两个输入。要添加第三个输入，你必须发挥创造力。最后，通常更容易将门对齐到相应输入端口的左侧，尽管也可以使用[anchor=in 1]（例如）将输入端口对齐到输出端口的右侧

我添加了文本字段只是为了跟踪哪个门是哪个门。满意后再删除它们。

这可能是另一种分布。

它不使用允许定义逻辑门输入数字的库circuittikz。circuits
