CNET Editors' review
Tutors and students for logic and computer programming will find this application for minimizing, simplifying and reducing Boolean equations and digital logic circuits a handy box of tools for increasing understanding.
Simple Solver launches a rather plain but functional interface. The large, mostly empty window includes a selection of buttons and check boxes accompanying two medium-size panes or sections, depending on the process being performed. The two panes or sections serve as an editor for inputting equations or criteria and for displaying output from the processes performed on the specified equations. The lack of clutter on the interface provides clarity that helps focus the user's attention on the app's operations--flashy colors and intricate designs don't affect the black-and-white facts of mathematics.
This free toolbox performed very well during our tests. It responded quickly to all our clicks and commands. We liked the array of example equations built into Simple Solver, which provide tutors a nice basis for exploring Boolean equations, the permutation function, random numbers, the simulation function, and the synthesis function. Selecting a process to run was a very straightforward matter of choosing a check box: minimize, invert and minimize, truth table, sort names, and show only last for Boolean processes, and similar simple choices for the other processes. We also liked that we could print either the input or output, allowing teachers to build a study guide or test very easily. We wished we could save items in more formats other than just text, but at least text-formatted files can be converted to other formats.
From David Baldwin:
Simple Solver is a free Windows application that can simplify Boolean equations, truth tables and digital logic. The application includes six different tools: Boolean, Logic Design Draw, Logic Design Auto, Logic Simulation, 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. 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.
Logic Design Draw - A graphical WYSIWYG tool that enables a user to interactively create a logic schematic diagram and to run circuit simulation. Signals can be added, renamed or deleted; parts can be added or deleted; and connections can be changed. After each change the circuit is automatically re-drawn and the simulation is automatically re-run. Logic Design Auto - Automatically design small digital logic circuits and state machines from timing diagrams or truth tables. All circuit types and configurations are supported: Combinational, Sequential, Synchronous and Asynchronous.
What's new in this version: Version 4.3.5 increases Output signals and Compare Words from 1 to 4. Updated name-group Help documentation. LDD - Enabled Drag-Drop.

"My Vista 64 wouldn't take it. worked a bit fun crashed"
Version: Simple Solver 3.3.1
The little it worked was fun.
I got a warning after download scan saying seldom downloaded could be dangerous. I tried it anyway and then after a day of fun it crashed my machine. Hope they get the bugs out?
I really hope as time goes on they get the bugs out and it downloads clean I really was enjoying the thing the little it worked>
"It works well for generating truth tables"
Version: Simple Solver 3.0
It works well
I haven't found any
I've used this program only to generate truth tables for logical equations. And it works very well for this purpose.
