In the interactive animation mode the simulator processes input commands and displays output values The input components, on the left of the figure, are a clock and a logical level generator The level generator is represented as a switch, toggled by a mouse click The clock can be activated edge by edge or continously Timing diagram simulation is the most common tool to check circuits’ functionality d-DcS Simulation features are similar to those of professional tools Clock and input signals can be easily edited Several input sequences can be saved with the circuit file. Saved sequences are useful for testing purposes and, in general, for educational applications

The browsers show a list of the assignments and a specific assignment.
Text and objects in the page can be active, i.e. associated to simulation functions.
The browser interacts with simulators, providing a true interaction between problems and experiments (e.g. by clicking on the schematics, the circuit is loaded in the Digital Circuit Simulator, and can be tested or modified)
