+\subsection{RTLIL without memories and processes}
+
+\begin{frame}[fragile]{\subsecname}
+After the command {\tt proc} and {\tt memory} (or {\tt memory -nomap}), we are left with a much simpler version of RTLIL:
+
+\begin{center}
+\begin{tikzpicture}[scale=0.6, every node/.style={transform shape}]
+	\tikzstyle{entity} = [draw, fill=gray!10, rectangle, minimum height=3em, minimum width=7em, node distance=5em, font={\ttfamily}]
+	\node[entity] (design) {RTLIL::Design};
+	\node[entity] (module) [right of=design, node distance=11em] {RTLIL::Module} edge [-latex] node[above] {\tiny 1 \hskip3em N} (design);
+
+	\node[entity] (wire) [fill=blue!10, right of=module, node distance=10em] {RTLIL::Wire} (wire.west) edge [-latex] (module);
+	\node[entity] (cell) [fill=blue!10, above of=wire] {RTLIL::Cell} (cell.west) edge [-latex] (module);
+\end{tikzpicture}
+\end{center}
+
+\bigskip
+Many command simply choose to only work on this simpler version:
+\begin{lstlisting}[xleftmargin=0.5cm, basicstyle=\ttfamily\fontsize{8pt}{10pt}\selectfont]
+if (module->processes.size() != 0 || module->memories.size() != 0)
+    log_error("This command does not operate on modules with processes "
+              "and/or memories! Run 'proc' and 'memory' first.\n");
+\end{lstlisting}
+
+\bigskip
+So we only discuss this version of RTLIL in this presentation.
