Simple Solver is a free Windows application that can simplify computer logic systems, Boolean equations, and truth tables. The application includes six different tools:Logic Design Draw, Logic Simulation, Logic Design Auto, Boolean, Permutation and Random Number. These tools are built on years of engineering design experience and are intended for both educational and industrial usage. The software is available as freeware for download. Logic Design Draw - A hierarchical WYSIWYG tool that enables a user to interactively create a logic schematic diagram and to run circuit simulation. Logic circuits can be very simple, such as and-or logic, or can consist of hundreds of parts. Both basic parts (logic gates, flip-flops) and MSI (Medium Scale Integration) building blocks are provided. Using blocks, large hierarchical designs - such as small computers - can be built. Computer Logic Simulation - Evaluates both logic circuit functionality and timing problems such as flip-flop setup and hold times, race conditions and glitches/spikes. All circuit types and configurations are supported: Combinational, Sequential, Synchronous and Asynchronous. Logic Design Auto - Automatically design small digital logic circuits and state machines from timing diagrams or truth tables. Boolean - Generates minimized Boolean equations from Boolean equation or Truth table inputs. Boolean operator formats are supported for a variety of languages including: ABEL, C, C++, PALASM, VB, Verilog and VHDL. The software uses both Quine-McCluskey and Espresso (UC Berkeley) algorithms to optimize minimization. Permutation - Generates permutations of numbers from a specified base number and a specified number of digits. Can be used for a variety of applications such as generating binary, octal or decimal number tables. Random Number - Generates from 1-99,999 random numbers in a specified range between -99,999 to 99,999.
