我已经访问了太多页面，但我还没有找到任何类似于 draw 或 draw 的页面

点赞节点图片
问题不太好（没有 MWE），OP 也不太主动与帮助者沟通。然而，这个图的复杂性吸引了我。我密集使用了几个锚点类似节点pic simcard、simsource，以及一个奇怪的（用户定义的）形状，如节点 pic snode。这里既没有使用，[name prefix]也没有使用， ... 。如果有更简单的方法（TikZ 或其他），我会感到惊讶。(-parent)(-children)
这种使用 s 的方式pic几乎和 s 一样灵活node。特别是，这种方式可以处理这里和这里。

老的这是给你的建议——左边的方块。同样，你也可以画右边的方块。
我定义了一个pic命名的simcard（看起来像这样^^）。命名 apic在某种程度上是有限制的，但在这种情况下就足够了。里面pic有 3 个坐标：-element、-parent和-parent。因此，在命名该图片后，比如L，然后你可以将它们重新用作(L-element)、L-parent和L-parent。
PS：您也可以将左边和右边画成独立的图形。
\documentclass[tikz,border=5mm]{standalone}
\begin{document}
\begin{tikzpicture}
\tikzset{simcard/.pic={
\draw (0,1)--(0,-1) (0,0)--(-2,0);
\draw[rounded corners=3mm,very thick] (1,1) rectangle (-2,-1);
\fill
(.5,0) circle(3pt) coordinate (-element)
(-1,.5) circle(3pt) coordinate (-parent)
(-1,-.5) circle(3pt) coordinate (-children)
