如何在矩形/盒子中制作不同大小的部分？

Question

我受到这张图片中 HAL 的展示的启发，并想在乳胶中制作一些差不多相同的东西。

这是我当前的代码：

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{pgfgantt}
\usepackage{float}

\definecolor{gray}{rgb}{0.5,0.5,0.5}
\definecolor{darkgray}{rgb}{0.66,0.66,0.66}
\definecolor{black}{rgb}{0,0,0}
\definecolor{white}{rgb}{1, 1, 1}


\tikzset{block/.style={rectangle, draw, fill=gray!50,
text width=10em, text centered, rounded corners=0pt, minimum height=0em}}

\title{boxes}
\date{February 2020}

\begin{document}

\maketitle

\begin{figure}[H]
        \centering
        \begin{tikzpicture}
        \node[block, minimum height=2cm, xshift=2cm] (task) {Tasks};
        \node[block, minimum height=2cm, fill=darkgray!150, below=of task, yshift=1cm] (executive) {Executive};
        \node[block, minimum height=3cm, yshift=1cm, below=of executive] (driver) {Drivers};
        \node[block, minimum height=1cm, below of=driver, xshift=0.53cm, text width=7em] (hal) {Hardware abstraction layer};
        \node[block, minimum height=2cm, below=of driver, yshift=1cm](hardware) {Hardware};

        \end{tikzpicture}

        \caption{\label{fig:Fig1_ecosystem}HALs place in the hierarchy of the executionpath}

    \end{figure}

\end{document}

这是输出：
