产生以下输出：

拓扑

如您所见，我使用了 3 个 Circuitikz 图形来绘制每个拓扑。我的目标是创建这样的 Tikzpicture：

目标

但我不知道如何将这些图形放入一张新图片中，所以我可以使用通用坐标来创建图片。

编辑：好的，我已经将我的 CircuitikZ 图片嵌入到树木环境中：

它看起来像这样：

树

但我不知道如何实现 4 级（Zustandsraum）节点，以及如何将它们合并到 5 级（SSA）。

答案1

通常强烈建议在节点中\savebox使用 a 时使用 es tikzpicture。这也适用于节点的内容forest，我将使用它来绘制此图。因此电路进入forest节点，其余部分或多或少是标准的，但需要注意的是，树的下半部分是手工绘制的，因为实际上不支持合并分支。除此之外，我将示例简化为更简单的内容。

答案2

嵌套tikzpicture通常是不受欢迎的（在这里搜索“嵌套 tikzpicture”...），因为结果无法保证。

在这些情况下，当电路必须重复时，我通常会定义一个宏来绘制相对于参数（即坐标）的电路。在宏中，我定义了一组coordinates，它们随后可用于构建图表的其余部分。

以下只是一个小例子，但希望可以给你一点启发。

\documentclass[border=10pt]{standalone}
\usepackage[siunitx, RPvoltages]{circuitikz}
\usetikzlibrary{calc}
%\usectikzstyle{romano}
\newcommand{\mycirc}[3][]{% define the circuit relative to the (external)
    % coordinate; use as  \mycirc[options]{coord}{name}
    % it will define the coordinate nw-name, sw-name etc. for further references
    \begin{scope}[#1]
        \draw #2 coordinate (start)
        to[V] ++(0,2) to[short, *-*]
        ++(2,0) coordinate(R) to [D] (R|-start)
        to [short, *-*] (start);
        \path (start) ++(-1,-1) coordinate(sw-#3)
        (R) ++(1,1) coordinate (ne-#3)
        (sw-#3 |- ne-#3) coordinate (nw-#3)
        (sw-#3 -| ne-#3) coordinate (se-#3);
        \draw [thin] (sw-#3) rectangle (ne-#3);
    \end{scope}
}
\begin{document}
\begin{circuitikz}
    \mycirc{(0,0)}{top}
    \mycirc[scale=0.7, transform shape]{(-5,-7)}{left}
    \mycirc[scale=0.7, transform shape]{(6,-7)}{right}
    \draw[red] ([yshift=-0.2cm]$(sw-top)!0.5!(se-top)$) -- ++(0,-0.5) coordinate(a);
    \draw [red,->] (a) -| ([yshift=0.2cm]$(nw-left)!0.5!(ne-left)$);
\end{circuitikz}
\end{document}
