如何使用 tikz-cd 绘制下图？

Question

如何使用 tikz-cd 绘制该图？

Here is my code

\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{shapes,arrows,shapes}
\begin{document}
    \tikzstyle{block} = [draw,rectangle,node distance=5em]
    \tikzstyle{line}=[draw,-stealth]
\begin{tikzpicture}
\node[block] (1) {Reserved};
\node[block, right of=1] (2) {Aero length};
\node[block,right of=2] (3) {DET};
\node[block,right of=3] (4) {Bob's Signature};
\node[block,right of=4] (5) {CPU};
\node[block,right of=5] (6) {Working};
\node[block,below of=1] (7) {Subframe 1};
\node[block,below of=2] (8) {Subframe 2};
\node[block,below of=3] (9) {Subframe 3};
\node[block,below of=4] (10) {...};
\node[block,below of=5] (11) {Subframe N};
\path[line](9)--(1);\path[line](11)--(6);
\node[block,below of=7] (12) {Memory};
\node[block,below of=9] (13) {ALU};
\path[line](13)--(7);\path[line](13)--(11);
\end{tikzpicture}
\end{document}

这种组可以用 轻松绘制matrix of nodes。以下代码显示了此选项：

\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{arrows,matrix,positioning}
\begin{document}
\begin{tikzpicture}[
    field/.style={draw, rounded corners, minimum height=8mm, anchor=center, align=center},
    frame/.style={matrix of nodes, column sep=-\pgflinewidth, nodes={field}}]

    \matrix (F1) [frame, row 1/.style={nodes={field, minimum height=12mm, text width=16mm}}]{
    Reserved & {Areo \\ length} & DET & {Bob's\\ signature} & CPU & working \\};

    \matrix (F2) [frame, below=of F1]{
    Subframe 1 & Subframe 2 &|[minimum width=2cm]| \dots & Subframe n \\};

    \matrix (F3) [frame, below=of F2]{
    Memory & |[minimum width=6cm]| ALU \\};

    \draw[dotted] (F1-1-1.south west) -- (F2-1-2.north west);
    \draw[dotted] (F1-1-6.south east) -- (F2-1-2.north east);
    \draw[dotted] (F2-1-1.south west) -- (F3-1-2.north west);
    \draw[dotted] (F2-1-4.south east) -- (F3-1-2.north east);
\end{tikzpicture}
\end{document}

更新：

如果没有mimimum width或text width固定，则所有节点都会根据其大小进行调整。如果您想要换行（如 中所示Aero length），text width则{...}需要使 breakline 命令 ( \\) 起作用。

\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{arrows,matrix,positioning}
\begin{document}
\begin{tikzpicture}[
    field/.style={draw, rounded corners, minimum height=8mm, anchor=center, align=center},
    frame/.style={matrix of nodes, column sep=-\pgflinewidth, nodes={field}}]

    \matrix (F1) [frame, row 1/.style={nodes={minimum height=12mm}}]{%
    Reserved&|[text width=1cm]|{Areo\\ length}&DET&|[text width=14mm]|{Bob's\\ signature}&CPU&working\\};

    \matrix (F2) [frame, below=of F1]{%
    Subframe 1&Subframe 2&\dots&Subframe n\\};

    \matrix (F3) [frame, below=of F2]{%
    Memory&ALU\\};

    \draw[dotted] (F1-1-1.south west) -- (F2-1-2.north west);
    \draw[dotted] (F1-1-6.south east) -- (F2-1-2.north east);
    \draw[dotted] (F2-1-1.south west) -- (F3-1-2.north west);
    \draw[dotted] (F2-1-4.south east) -- (F3-1-2.north east);
\end{tikzpicture}
\end{document}
