NAME

       logisim - a graphical tool for designing and simulating logic circuits

SYNOPSIS

       logisim

DESCRIPTION

       logisim	is  an	educational  tool for designing and simulating digital logic circuits. With its simple toolbar interface and simulation of
       circuits as you build them, it is simple enough to facilitate learning the most basic concepts related to logic circuits. With the capacity
       to build larger circuits from smaller subcircuits, and to draw bundles of wires with a single mouse drag, Logisim can be used (and is used)
       to design and simulate entire CPUs for educational purposes.

NAME

       boolstuff - Disjunctive Normal Form boolean expression C++ library

SYNOPSIS

       g++ prog.cpp -lboolstuff

DESCRIPTION

       boolstuff  is  a  C++ library that contains an algorithm to convert a boolean expression binary tree into the Disjunctive Normal Form.  The
       NOT operator is supported.  A C API covers most of the library's functionality.

       The Disjunctive Normal Form is an ORing of ANDed terms.	In other words, if the OR is considered an additive operation and the AND a multi-
       plicative operation, then the DNF is a sum of products.

       For example, the DNF of the expression a&(b|c) is a&b|a&c

       The DNF eliminates parentheses and provides a normalized form of the original expression.  This normalized form is easier to execute.

       The  DNF produced by BoolStuff is devoid of any "useless" terms, which are always false (e.g., x&y&!x), but the terms that form the DNF are
       not necessarily simplified (e.g., x&y&x).  When executing an expression in DNF, it is recommended to obtain the list of terms and  then	to
       obtain the set of variables used in each term.  In the case of the term x&y&x, the set will only contain x once.

EXAMPLES

       The library's source archive comes with an example program (in the 'examples' subdirectory) and with two testing programs (in the src/bool-
       stuff subdirectory).

BUGS

       Version	0.1.x is an unstable development version.  The programming interface of the library and the command-line options of the accompany-
       ing commands are not necessarily fixed.	The documentation has not been reviewed for completeness.

HISTORY

       George Boole (1815-1864) is an English mathematician who helped establish modern symbolic logic and whose  algebra  of  logic,  now  called
       Boolean algebra, is basic to the design of digital computer circuits.
