	DipTrace Free  License: Freeware
	DipTrace is an advanced PCB design software application that consists of 4 modules: PCB Layout with efficient auto-router, Schematic Capture, Component and Pattern Editors that allow you to design your own component libraries. Besides being very simple to learn, this software has a very intuitive user interface and many innovative features. For instance, a schematic can be converted to a PCB with one mouse click. Advanced manual placement and auto-placement features allow to get acceptable placement in several minutes. The board designer can instantly renew the PCB from an updated version of schematic and keep all previous work without changes. PCB and Schematic can be compared at any design stage to ensure they are identical. DipTrace has a powerful automatic router. It can route a single layer and multilayer circuit boards, and there is an option to autoroute a single layer board with jumper wires, if required. DipTrace also provides you with external autorouter support. Smart manual routing tools allow users to finalize the design and to get the results they want in a blink of an eye. Accurate shape-based copper pour system with different possible fill types and thermals can be used to make planes or to reduce manufacturing costs. Other important features are Electrical Rule Check (ERC), Design Rule Check (DRC) and Net Connectivity Check - the functions that check connections in Schematic by different rules (pin type, short circuit, etc.), the clearance between layout objects, which ensures board accuracy, and connectivity of all nets not depending on how they are connected (with traces, thermals or shapes). DipTrace modules allow you to exchange schematics, layouts and libraries with other EDA and CAD packages. DipTrace Schematic Capture and PCB Layout also support popular netlist formats and spice. Output formats are DXF, Gerber, Drill and G-code. Standard libraries include 50.000+ components. Author: Novarm, Ltd.| Date: 06-03-2007 | Size: 29988 KB

	Atanua  License: Freeware
	Atanua is a real-time logic simulator designed for educational use. It has an intuitive, OpenGL accelerated user interface, with which the user can place components and wires. Components include all common logic blocks, including gates, latches and flipflops. Additionally Atanua simulates about 30 different 74-series chips, as well as an 8051 microcontroller variant. Simulated and pure logic parts can be mixed in the same circuit. On the I/O front, Atanua includes several different frequency clock inputs, constant level inputs as well as buttons that are bound to the user's keyboard. LEDs in various colors as well as 7-segment displays are also included. There is also a simple logic probe for debugging. The simulated parts are designed to resemble their real-world counterparts, which is more attractive for the students than pure schematics. The students can practice lab experiments using the simulated chips. The simulation shows the signal state of each wire in real time. In addition to high and low signal level, parts may output "invalid" signal, stating that there is a problem with the circuit, such as outputs connected together, or missing wirings from some chip. Additional parts can be made using the plug-in interface. As an example plug-in, a driver for the Velleman K8055 USB experiment board is provided, with which the user can mix simulated and real-world components. An anti-cheating tool is also available for teachers who wish to use Atanua for homework. Author: Jari Komppa| Date: 27-03-2008 | Size: 1598 KB

	Circuit Weaver  License: Freeware
	Circuit Weaver is a completely original game in which you move your energy mass around a circuit by rearranging the circuit elements. The energy mass will follow the paths you create for it, activating "Zero Power" chips as you lead the mass to them. You have to make sure you don't lead the energy mass off the circuit board, and that you don't send it into energized circuitry to survive this game. To make things even more interesting, you'll be preserving a fine balance as you will need to use energy to rearrange the circuit board, and will also gain some energy as you send your energy mass on its way. As you get to higher levels, a time factor will be introduced into the game by having a real time enemy follow you around. As you progress through the levels, yet another puzzle aspect will present itself into the game, as you will need to maneuver your energy mass, while avoiding its on trail (energized circuits). This situation creates yet another puzzle element that resembles that which you get in a game like Tron, or Light Cycle. A fun, and fast paced puzzle game that offers many puzzle, and even real time aspects that will keep you entertained for days, even weeks! Author: best3dgames.net| Date: 18-06-2006 | Size: 518 KB
