boolgen 1.1.0

A library for generating and simplifying Boolean expressions from truth tables

boolgen

boolgen is a Python library and command-line tool for generating and simplifying Boolean expressions from truth tables.

The library implements a version of the Quine-McCluskey method to perform the simplification. I created it to help with designing digital logic circuits from truth tables.

Installation

To install boolgen, use pip:

pip install boolgen

If you download the source, you can run the unit tests.

Command-Line Interface

The boolgen tool can be used from the command line to process truth tables stored in files and output simplified Boolean expressions.

Syntax

boolgen <input_file>

• <input_file>: Path to the input file containing the truth table.

If no filename is provided, then boolgen will try to read the table from STDIN.

Example Input File

Create a file named input.txt with the following content:

A B C D= E=
0 0 0 0 1
0 0 1 1 0
0 1 0 1 0
1 0 0 1 0
1 1 1 0 1

Input and output variables can be identified with any alphanumeric string (including underscores). Output variables are identified by a pre- or postfix '='. If no output variable is explicitly declared, the last column in the table is assumed to be the output.

Output

boolgen will output the simplified Boolean expressions for each output variable in the truth table.

D = A | B & ~C
E = ~A & ~B & ~C | A & B & C

In degenerate cases, an output variable might be set to 0 or 1.

Library

You can also import boolgen into your own project. See the function definitions for an idea of how it all works.
