Atanua Description

Atanua - A real-time logic simulator, designed to help in learning of basic boolean logic and electronics Atanua is a real-time logic simulator, designed to help in learning of basic boolean logic and electronics. Atanua uses OpenGL hardware-accelerated rendering and a custom UI designed for a very low learning curve and a fast workflow, allowing the students to concentrate on learning the subject instead of spending time learning the tool.The Atanua UI consists of basically three parts:· the component list· the work area· buttons for some useful functions, like saving and loadingHere are some key features of "Atanua":· Intuitive, hardware-accelerated interface.· Available for Windows, Linux and Mac os X.· Real-time logic simulation (at 1000Hz).· Most common logic blocks, with both US and Finnish symbols.· Simulation of various 74-series chips.· Simulation of a 8051 microcontroller variant.· Input through keyboard-bound buttons, output through various LEDs and 7-segment displays.· Plug-in interface for creation of custom parts.· Instant feedback through wire colors, which show signal states and error states.· Helpful tooltips.· Anti-cheating tool available for teachers for homework validation.The base logic parts come in ANSI and Finnish symbol versions. The texture is different, underlaying code is the same.Base parts list:· Logic '0' (ground) and '1' (vcc)· Logic AND, OR, NAND, NOR, XOR and NOT gates, in both US and Finnish symbols· SR-latch (NOR and NAND versions), Synchronized SR-latch, D-latch, T-latch, JK-latch· JK-flipflop, D-flipflop, T-flipflop, SR-flipflop· 2-bit MUX block, 3-bit DX-block· Synchronized clock generators (0.1Hz, 0.2Hz, 0.5Hz, 1Hz, 2Hz, 5Hz, 10Hz, 20Hz, 50Hz, 100Hz, 200Hz, 500Hz)· LabelsChips list:· 7400 - Quad 2-input NAND Gate· 7402 - Quad 2-input NOR Gate· 7404 - Hex Inverter· 7408 - Quad 2-input AND Gate· 7410 - Triple 3-input NAND Gate· 7420 - Dual 4-input NAND Gate· 7432 - Quad 2-input OR Gate· 7447 - BCD to 7-segment Decoder/Driver· 7473 - Dual J-K Flip-Flop with Clear· 7474 - Dual D Positive Edge Triggered Flip-Flop with Preset and Clear· 7485 - 4-bit Magnitude Comparator· 7486 - Quad 2-input XOR Gate· 7490 - Decade Counter (separate Divide-by-2 and Divide-by-5 sections)· 74138 - 3 to 8-line Decoder/Demultiplexer· 74139 - Dual 2 to 4-line Decoder/Demultiplexer· 74151 - 8-Line to 1-Line Data Selector/Multiplexer· 74154 - 4-Line to 16-Line Decoder/Demultiplexer· 74181 - 4-bit Arithmetic Logic Unit and Function Generator (may contain some bugs due to complexity of the chip)· 74191 - Synchronous Up/Down Binary Counter· 74195 - 4-bit Parallel-Access Shift Register· 74240 - Octal Buffer with Inverted Three-State Outputs· 74241 - Octal Buffer with Noninverted Three-State Outputs· 74244 - Octal Buffer with Noninverted Three-State Outputs· 74245 - Octal Bus Transceiver with Noninverted Three-State Outputs· 74163 - Synchronous 4-bit Binary Counter with Synchronous Clear· 74164 - 8-bit Parallel-Out Serial Shift Register with Asynchronous Clear· 74283 - 4-bit Binary Full Adder· 74574 - Octal D-Type Edge-Triggered Flip-Flop with Three-State Outputs· 2051 - 20-pin 8051-variant 8-bit Microcontroller with 2K Bytes Flash and 15 Programmable I/O LinesI/O parts list:· LEDs (red, green, blue, cyan, magenta, yellow, white), normal and inverted· 7-segment displays in same colors, normal and inverted· Keyboard keys (0,1,2...9, a,b,c...z)· Simple logic probe· Simple audio outputNote: Free for personal, non-commercial use only.
