Introduction - Presentation Feb 11, 2006

This is a program being developed by me to allow students to draw and examine logic circuits with flip-flops.

Features:

Open source, written in Java
Runs as either an applet or an application
Uses plain text files to save and restore the state of the simulation
Prints the simulation
Supports animation of minterm inputs, flip-flop clock ticks, and toggling input and flip-flop values
Other features will be added as I have time

Versions:

Version	Run Applet	Documentation (inlcudes links to source code and a longer documentation file)	Examples	Comments
v 0.7.1.07 Feb 17, 2008	Run the applet with basic logic circuit examples Run the applet with test examples Run with Mano Lessons Run with Carpinelli Lessons	Installation Notes by JackHirschfelder Get the jar file javadoc source code GPL Used to prepare a FSM Help File	See Lessons in Program Source for Lessons in Program Suggested problems	Requires Java version 5.0 - Added group move, document awareness, task gates Added Lessons, including allowing links to other Lessons Added PLA and Box components Same file format as v5, uses tear-off menus Simplified the Lessons menu file format. Added the basic lessons. Cleaned up some problems. Added lessons for Carpinelli and Mano texts Will send image to clipboard when run as an application Added arrows to drawings. Can color comment backgrounds. Undo new component and move using cntrl-Z Some boxes resize to label
v5 Mar 22, 2005	-	-	-	Requires Java version 1.4 The file format has changed again, v4 and v3 files won't work here. This version has comment gates, and allows labels with spaces Print scales and adds date to output Add dots is now active.
v4 Mar 14, 2005	-	-	-	Requires Java version 1.4 Cleared up some issues: printing, remove indeterminant states, changed some colors, added labelling, I/O preserves labels, so data files from v3 won't work with this version. Right-click on component to change label. Add Dots is not active yet.
v3	-	-	-	Requires Java version 1.4 Added flip-flops, useful documentation The examples may be copied into the Text IO windows and then loaded. Figures and Problems are from Mano, 3rd edition.
v2	-	-	-	Added floating menus, printing, and text I/O
v1	-	-	-	First working version, doc mostly requirements
