是否可以使用 circuitikz 实现多个输入逻辑端口？

如果 TikZ 有它们，那不可能是全部那难的。

\documentclass{standalone}
\usepackage{circuitikz}
\makeatother
\begin{document}
\begin{circuitikz}
\node[american and port] at (0,0) {};
\node[american nand port] at (0,-2) {};
\node[american or port] at (2,0) {};
\node[american nor port] at (2,-2) {};
\node[american xor port] at (4,0) {};
\node[american xnor port] at (4,-2) {};
\end{circuitikz}
\end{document}

TikZ 用于\pgfutil@g@addto@macro创建锚点，这些锚点可能以某种未记录的命名约定保存为全局宏。关键似乎是编写一个宏 ( )，它将仅使用s 和一个输入 ( )\pgf@circ@logicport@input来定位锚点。\savedanchor\pgfmathcounter

另一个问题是各个端口的左侧都是弯曲的，因此需要能够计算给定值的边缘位置y。为了简化这些计算，我使用圆弧代替\pgfpathcurveto。我还替换了外曲线。新形状不是完美匹配，但它们非常接近。为了定义左侧圆弧，我添加了两个新参数，angle和inner。 angle是起始角度，inner是从外边缘到曲线中间的距离。x 和 y 半径是使用计算的\pgfmath。（最终我用完了长度寄存器，不得不使用宏。）另一方面，所有aaa通过ddd参数都不再使用。

inputs按照 Circuitikz 的惯例，可以使用 为每种类型的门设置输入数量 ( ) \ctikzset。我添加了一个节点参数 ( number inputs)，可以根据每个节点进行设置。此外，这个数字绝不能小于 2 或大于 16。

我添加了origin参数。设置origin=0将中心锚点置于节点的中心。默认设置为 0.8，以实现向后兼容。我修复了锚点，text以便可以在端口内写入零件编号等（如果合适）。
