# kitty



kitty is a C++-17 truth table library.  It provides efficient implementations for basic truth table manipulations and various algorithms.

[Read the full documentation.](http://libkitty.readthedocs.io/en/latest/?badge=latest)

## Example

The following code snippet generates truth tables for the 3-variable functions `sum` and `carry` for a 1-bit full-adder with carry.

```c++

#include 

dynamic_truth_table a( 3 ), b( 3 ), c( 3 );

create_nth_var( a, 0 );

create_nth_var( b, 1 );

create_nth_var( c, 2 );

const auto sum = a ^ b ^ c;

const auto carry = ternary_majority( a, b, c );

```

One can use `static_truth_table` instead of `dynamic_truth_table`, if the number of variables is known at compile-time.  The interface stays the same.

```c++

#include 

static_truth_table<3> a, b, c;

create_nth_var( a, 0 );

create_nth_var( b, 1 );

create_nth_var( c, 2 );

const auto sum = a ^ b ^ c;

const auto carry = ternary_majority( a, b, c );

```

## EPFL logic sythesis libraries

kitty is part of the [EPFL logic synthesis](https://lsi.epfl.ch/page-138455-en.html) libraries.  The other libraries and several examples on how to use and integrate the libraries can be found in the [logic synthesis tool showcase](https://github.com/lsils/lstools-showcase).
