<img src="https://cdn.rawgit.com/msoeken/kitty/master/kitty.svg" width="64" height="64" align="left" style="margin-right: 12pt" /> kitty is a C++-17 truth table library. It provides efficient implementations for basic truth table manipulations and various algorithms.

Read the full documentation.

Example

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

#include <kitty/kitty.hpp>

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.

#include <kitty/kitty.hpp>

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 );
