Logisim -Simulate Digital Logic Circuits

Logisim is an educational tool for designing and simulating digital logic circuits. With its simple toolbar interface and simulation of circuits as you build them, it is simple enough to facilitate learning the most basic concepts related to logic circuits.

Logisim -Simulate Digital Logic Circuits

Logisim -Simulate Digital Logic Circuits

With the capacity to build larger circuits from smaller subcircuits, and to draw bundles of wires with a single mouse drag, Logisim can be used (and is used) to design and simulate entire CPUs for educational purposes.

Some Features
  • The wiring tool draws horizontal and vertical wires, automatically connecting to components and to other wires. It's very easy to draw circuits!
  • Circuit layouts can be used as "subcircuits" of other circuits, allowing for hierarchical circuit design.
  • Included circuit components include inputs and outputs, gates, multiplexers, arithmetic circuits, flip-flops, and RAM memory.
  • The included "combinational analysis" module allows for conversion between circuits, truth tables, and Boolean expressions.

Embedded Development using VisSim - Visual Solutions

VisSim is a software tool by which we can do mathematical modeling, simulation, and model-based embedded development with a friendly and easy visual language.

Embedded Development using VisSim - Visual Solutions

"VisSim is a block diagram language for creating complex nonlinear dynamic systems. To create a model, simply drag blocks in the workspace and connect them with wires. Then click the Go button to initiate your simulation. The response is instantaneous."

 "VisSim's tightly integrated development platform makes it easy to pass freely among the stages of model construction, simulation, optimization, and validation. This means you can create virtual prototypes on your desktop and make sure they're working properly before committing to the design."
