在tikz中围绕另一个节点绘制U形节点

Question

作为报告格式说，你可能不想使用node形状乌，这会相当复杂。不过，你可以利用它nodes得到正确的形状：

\documentclass[tikz]{standalone}

\usetikzlibrary{arrows.meta}

\begin{document}
    \begin{tikzpicture}[
            workerWidth/.style={minimum width=3cm},
            workerHeight/.style={minimum height=2cm},
            UWidth/.style={minimum width=1cm},
            every node/.style={
                text centered,
                },
            thick
            ]
        \node[workerWidth, workerHeight, draw] (worker) at (0, 0) {Worker};

        \node[anchor=north, workerWidth, yshift=-0.5cm] (cache) at (worker.south) {Cache};

        \node[anchor=east, workerHeight, UWidth, xshift=-1cm] (left) at (worker.west) {};
        \node[anchor=west, workerHeight, UWidth, xshift=1cm] (right) at (worker.east) {};

        \draw (left.north west) -- (left.west |- cache.south) -- (right.east |- cache.south) -- (right.north east) -- (right.north west) -- (right.west |- cache.north) -- (left.east |- cache.north) -- (left.north east) -- cycle;

        \draw[<-, >={Latex}] (left.west) -- ++(-1, 0);
        \draw[->, >={Latex}] (left.east) -- (worker.west);
        \draw[->, >={Latex}] (worker.east) -- (right.west);
        \draw[->, >={Latex}] (right.east) -- ++(1, 0);
    \end{tikzpicture}
\end{document}

结果和你的图片很像：

为了更好地了解它的工作原理，我给帮助涂上了颜色nodes：

从这三个锚点开始，nodes它使用它们的基础锚点来构建乌形状，而样式确保所有节点nodes都有正确的大小（您可以为每个节点手动执行此操作，但这种方式可以确保一致性）。

如果你真的想要乌形节点，您可能需要提供更多信息并提供一些起始代码。这些东西相当复杂。
