I would like to draw the following pictureenter image description here

I have tried my best but nothing work. My code isn't really worth posting it here. The problem I'm facing is fitting blocks inside one block with proper connection between them. I have tried to use fit, but it is not working or I think I misuse it. Appreciate any help.


Edit:

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{calc,fit,arrows, positioning}
\usepackage{graphicx}
\begin{document}

\noindent\resizebox{\textwidth}{!}{
\begin{tikzpicture}[auto,node distance=5cm,>=stealth']
\tikzset{
block/.style= {draw, rectangle, minimum height=2em,minimum width=4em},
sum/.style = {draw, circle, node distance=2cm},
input/.style  = {coordinate},  
output/.style = {coordinate}}

\node [input, name=input](input) {};
\node [sum, right of=input] (sum) {$\sum$};
\node [block, right of=sum, minimum height=6cm, minimum width=8cm] (M) {};

\node [coordinate, below of=M, yshift=1cm] (link1) {};
\node [coordinate, above of=M, yshift=-1cm] (link2) {};


\draw [-] (link1) -- node {} (M) ;
\draw [->] (link2) -- node {} (M) ;
\draw [<-] (sum) |- node[yshift=3cm, xshift=-.5cm] {$text$} (link1) ;



\node [block, right of=M,  rotate=90, minimum width=6cm] (n) {$\textbf{text}$};


\node [block, right of=n, minimum height=6cm, minimum width=5cm] (s) {text};
\node [coordinate, above of=s, yshift=-1cm] (link3) {};
\draw [-] (link3) -- node {} (s) ;
\draw [->] (input) -- node {$text$} (sum);
\draw [->] (sum) -- node {} (M);
\draw [->] (M) -- node {$text$} (n);
\draw [->] (n) -- node {$text$} (s);
\draw [-] (link3) -- node[yshift=.6cm,xshift=-5cm] {text} (link2);

\end{tikzpicture}
}


\end{document}

Would this be what you seek? styledefinitions block is for horizontal blocks, blockB is for vertical blocks (being rotated 90). all text phrases are allocated via node with options like above, below, above left, above right, etc., you may want to adjust to fit your needs.

Update: Small modifications to fit the OP's need. Some explanations are added. See %<---

  • Thank you so much @Jesse. I need just a minor modification shown in this picture. i59.tinypic.com/xmnyfs.png I need only to make the last box in the right to be horizontal and shifting the two right boxes to the right so that the box in the left has more space. Thank you so much again. – CroCo Sep 15 '14 at 8:49
  • @CroCo -- Please see my update. I have also added some texts explaining why such change will meet you need (I hope, :-)). – Jesse Sep 15 '14 at 10:40
  • Thank you so much @Jesse. I really appreciate your help. – CroCo Sep 15 '14 at 19:21
