-\subsection{Logic Gate Shapes}
-
-\subsubsection{Overview}
- \pgfname{} provides two libraries of logic gates, one providing
- ``American'' style gates and the other, providing ``rectangular''
- logic gates.
- Each library suffixes the gate names with an identifer:
- |US| for the American style gates, and |IEC| for the rectangular
- gates (additionally, two shapes in the |US| library use the
- suffix |CDH|). Keys which are specific
- to a particular library also contain this identifier (e.g.,
- |/pgf/and gate IEC symbol|).
- However, as described below, a \tikzname{} key is provided which
- sets up several styles allowing the identifier to be omitted,
- for example, |and gate| can become a synonym for |shape=and gate US|.
-
- Multiple inputs can be specified for a logic gate (provided they
- support multiple inputs: a not gate --- also known as an inverter ---
- does not). However, there is an upper limit for the number of inputs
- which has been set at 1024, which should be \emph{way}
- more than would ever be needed.
-
- There are some \pgfname{} keys which are common to both
- libraries, which have no library identifier contained in them:
-
-
- \begin{key}{/pgf/logic gate inputs=\meta{input list} (initially \char`\{normal,normal\char`\})}
- Specify the inputs for for the logic gate. The keyword |inverted|
- indicates an inverted input which will mean \pgfname{} will draw a
- circle attached to the main shape of the logic gate. Any keyword
- that is not |inverted| will be treated as a ``normal'' or
- ``non-inverted'' input (however, for readability, you may wish to
- use |normal| or |non-inverted|), and \pgfname{} will not draw the
- circle.
- In both cases the anchors for the inputs will be set
- up appropriately, numbered from top to bottom |input 1|, |input 2|,
- \ldots and so on. If the gate only supports one input the anchor
- is simply called |input| with no numerical index.
-
-\begin{codeexample}[]
-\begin{tikzpicture}[minimum height=0.75cm]
- \node[and gate IEC, draw, logic gate inputs={inverted, normal, inverted}]
- (A) {};
- \foreach \a in {1,...,3}
- \draw (A.input \a -| -1,0) -- (A.input \a);
- \draw (A.output) -- ([xshift=0.5cm]A.output);
-\end{tikzpicture}
-\end{codeexample}
-
- For multiple inputs it may be somewhat unweildy to specify a long
- list, thus, the following ``shorthand'' is permitted (this is an
- extension of ideas due to Juergen Werber and Christoph Bartoschek):
- Using |i| for inverted and |n| for normal inputs, \meta{input list}
- can be specfied \emph{without the commas}. So, for example,
- |ini| is equivalent to |inverted, normal, inverted|.
-
-\begin{codeexample}[]
-\begin{tikzpicture}[minimum height=0.75cm]
- \node[or gate US, draw,logic gate inputs=inini] (A) {};
- \foreach \a in {1,...,5}
- \draw (A.input \a -| -1,0) -- (A.input \a);
- \draw (A.output) -- ([xshift=0.5cm]A.output);
-\end{tikzpicture}
-\end{codeexample}
-
-\end{key}
-
-
-The height of the gate may be increased to accommodate the number
-of inputs. In fact, it depends on three variables:
-$n$, the number of inputs, $r$, the radius of the circle used
-to indicate an inverted input and $s$, the distance between
-the centers of the inputs.
-The default height is then calculated according to the expression
-$(n+1)\times\max(2r,s)$. This then may
-be increased to accommodate the node contents or any
-minimum size specifications.
-
-The radius of the inverted input circle and the distance between the
-centers of the inputs can be customised using the following keys:
-
-\begin{key}{/pgf/logic gate inverted radius=\meta{length} (initially 2pt)}
- Set the radius of the circle that is used to indicate inverted
- inputs. This is also the radius of the circle used for the inverted
- output of the |nand|, |nor|, |xnor| and |not| gates.
-

-\subsubsection{US Logic Gates}
-
-\begin{pgflibrary}{shapes.gates.logic.US}
- This library provides ``American'' logic gate shapes whose names are
- suffixed with the identifier |US|. Additionally,
- alternative |and| and |nand| gates are provided which are based on the
- logic symbols used in A. Croft, R. Davidson, and M. Hargreaves (1992),
- \emph{Engineering Mathematics}, Addison-Wesley, 82--95. These two
- shapes are suffixed with |CDH|.
-\end{pgflibrary}
-
- To use the shapes in \tikzname{} without their suffixes, the
- following keys are provided:
-
-\begin{key}{/tikz/use US style logic gates}
- This allows the the shapes suffixed with |US| to be used without
- the suffix. So, for example, |and gate| becomes a synonym for
- |shape=and gate US|.
-\begin{codeexample}[]
-\tikz\node[draw, and gate US, red]{and};
-\space
-\tikz[use US style logic gates,blue]\node[draw, and gate]{and};
-\end{codeexample}
-\end{key}
-
-\begin{key}{/tikz/use CDH style logic gates}
- This key again allows the the shapes suffixed with |US| to be used
- without the |US| suffix. However, |and gate| becomes a synonym for
- |shape=and gate CDH| and |nand gate| becomes a synonym for
- |shape=nand gate CDH|, providing alternative symbols for these
- gates.
-
-\begin{codeexample}[]
-\begin{tikzpicture}[minimum height=1cm]
- \node[draw, and gate US, red] at (0,1.5) {and};
- \node[draw, nand gate US, red] at (2,1.5) {nand};
- \tikzset{use CDH style logic gates}
- \node[draw, and gate, blue] at (0,0) {and};
- \node[draw, nand gate, blue] at (2,0) {nand};
-\end{tikzpicture}
-\end{codeexample}
-\end{key}
-
-
-
-As described above, \pgfname{} will increase the size of the
-logic gate to accommodate the number of inputs, and the size
-of the inverted radius and the separation between the inputs.
-However with all shapes in this library, any increase in size
-(including any minimum size requirements) will be applied so that
-the default aspect ratio is unaltered. This means that changing
-the height will change the width and vice versa.
-
-The ``compass point'' anchors apply to the main part of the shape

-provides an additonal feature to facilitate the relative positioning
-of logic gates:
-
-\begin{key}{/pgf/logic gate anchors use bounding box=\meta{boolean} (initially false)}
-When set to |true| this key will ensure that the
-compass point anchors use the bounding rectangle of the
-main shape, which, ignore any inverted inputs or outputs, but
-includes any |outer sep|.
-This \emph{only} affects the compass point anchors
-and is not set on a shape by shape basis: whether the bounding
-box is used is determined by value of this key when the anchor
-is accessed.

-\subsubsection{IEC Logic Gates}
-
-\begin{pgflibrary}{shapes.gates.logic.IEC}
- This library provides rectangular logic gate shapes. These shapes
- are suffixed with |IEC| as they are based on gates recommended by
- the International Electrotechincal Commission.
-\end{pgflibrary}
-
- In order to use these shapes in \tikzname{} without the |IEC|
- suffix, the following key is provided:
-
-\begin{key}{/tikz/use IEC style logic gates}
- This allows the the shapes suffixed with |IEC| to be used without
- the suffix. So, for example, |and gate| becomes a synonym for
- |shape=and gate IEC|. In addtion the |IEC| specific keys can be
- used without |IEC|, so |and gate symbol| can be
- used for |and gate IEC symbol|.
-\end{key}
-
- By default each gate is drawn with a symbol, $\char`\&$ for |and| and
- |nand| gates, $\geq1$ for |or| and |nor| gates, $1$ for |not| and
- |buffer| gates, and $=1$ for |xor| and |xnor| gates. These symbols
- are drawn automatically (internally they are drawn using the
- ``foreground'' path), and are not strictly speaking part of the node
- contents. However, the gate is enlarged to make sure the symbols are
- within the border of the node.
- It is possible to change
- the symbols and their position within the node using the following
- keys:
-
-\begin{key}{/pgf/and gate IEC symbol=\meta{text} (initially \char`\\char\char`\`\char`\\\char`\&)}
- Set the symbol for the |and gate|. Note that if the node is filled,
- this color will be used for the symbol, making it invisible, so
- it will be necessary set \meta{text} to something like
- |\color{black}\char`\&|. Alternatively, the
- |logic gate IEC symbol color| key can be used to set the color
- of all symbols simultaneously.
-
- In \tikzname, when the |use IEC style logic gates| key has been
- used, this key can be replaced by |and gate symbol|.
-\end{key}
-
-\begin{key}{/pgf/nand gate IEC symbol=\meta{text} (initially \char`\\char\char`\`\char`\\\char`\&)}
- Set the symbol for the |nand gate|.
- In \tikzname, when the |use IEC style logic gates| key has been
- used, this key can be replaced by |nand gate symbol|.
-\end{key}
-
-\begin{key}{/pgf/or gate IEC symbol=\meta{text} (initially \char`\$\char`\\geq1\char`\$)}
- Set the symbol for the |or gate|.
- In \tikzname, when the |use IEC style logic gates| key has been
- used, this key can be replaced by |or gate symbol|.
-\end{key}
-
-\begin{key}{/pgf/nor gate IEC symbol=\meta{text} (initially \char`\$\char`\\geq1\char`\$)}
- Set the symbol for the |nor gate|.
- In \tikzname, when the |use IEC style logic gates| key has been
- used, this key can be replaced by |nor gate symbol|.
-\end{key}
-
-\begin{key}{/pgf/xor gate IEC symbol=\meta{text} (initially \char`\{\char`\$=1\char`\$\char`\})}
- Set the symbol for the |xor gate|. Note the necessity for braces,
- as the symbol contains |=|.
- In \tikzname, when the |use IEC style logic gates| key has been
- used, this key can be replaced by |or gate symbol|.
-\end{key}
-
-\begin{key}{/pgf/xnor gate IEC symbol=\meta{text} (initially \char`\{\char`\$=1\char`\$\char`\})}
- Set the symbol for the |xnor gate|.
- In \tikzname, when the |use IEC style logic gates| key has been
- used, this key can be replaced by |xnor gate symbol|.
-\end{key}
-
-\begin{key}{/pgf/not gate IEC symbol=\meta{text} (initially 1)}
- Set the symbol for the |not gate|.
- In \tikzname, when the |use IEC style logic gates| key has been
- used, this key can be replaced by |not gate symbol|.
-\end{key}
-
-\begin{key}{/pgf/buffer gate IEC symbol=\meta{text} (initially 1)}
- Set the symbol for the |buffer gate|.
- In \tikzname, when the |use IEC style logic gates| key has been
- used, this key can be replaced by |buffer gate symbol|.
-\end{key}
-
-\begin{key}{/pgf/logic gate IEC symbol align=\meta{align} (initially top)}
- Set the alignment of the logic gate symbol (in \tikzname, when the
- |use IEC style logic gates| key has been used, |IEC| can be omitted.
- The specification in \meta{align} is a comma separated list from
- |top|, |bottom|, |left| or |right|. The distance between the border
- of the node and the outer edge of the symbol is determined by the values
- of the |inner xsep| and |inner ysep|.
-
-\begin{codeexample}[]
-\begin{tikzpicture}[minimum size=1cm, use IEC style logic gates]
- \tikzset{every node/.style={nor gate, draw}}
- \node (A) at (0,1.5) {};

- }
-\end{tikzpicture}
-\end{codeexample}
-
-\end{key}
-
-
-\begin{key}{/pgf/logic gate IEC symbol color=\meta{color}}
- This key sets the color for all symbols simultaneously. This color
- can be overridden on a case by case basis by specifying a color
- when seting the symbol text.
