How to draw stack diagram with TiKz?

Question

I want to draw a stack diagram looks like this with TiKZ.

I wonder is there way to draw this diagram with automatic positioning like drawing Automaton? Any idea? Thanks in advance.

Answer 1

You could use the shapes.multipart library and use nodes with parts:

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{shapes.multipart}
\begin{document}
\begin{tikzpicture}[stack/.style={rectangle split, rectangle split parts=#1,draw, anchor=center}]
\node[stack=5]  {
\nodepart{two}a
\nodepart{three}b
\nodepart{four}c
\nodepart{five}d
};
\end{tikzpicture}

\end{document}

Answer 2

You may have a look at drawstack.sty, which provides a few simples macros to draw stacks (tailored for execution stack, with addresses, stack pointer, ...).
