#4 LEDs in modules


Hi there.

It would be nice if one could add LEDs in a module
(subcircuit) that really turn on and off during
simulation. It would also be nice if one could add
buttons which one could interact with during
simulation. Those elements should then "shine through"
(ie if they are in a subcircuit, they should still be
visible/usable in the outer circuit if wanted).

Especially for the digital simulation/design part, that
would be a great improvement (it came to my mind,
because I needed a 7-segment-display and a keypad in my

Thanks for considering that...

    I am not sure what you actually mean by

    1) "really turn on and off during simulation"
    2) "buttons to interact with", what type of interaction?

    Please give a more extensive description about this feature

    i think i know what he means; i've been using a program that had such components, let me try to explain:

    that program (multisim) has the defult dimulation set to transient, it has a very powerful engine wich does all the calculcations in real time; when you start the simulation, all the simulation parameters gets auto-set (can be set manually too), and the simulation start running for an indefinite time (actually it has it's own limits, but depending on the setting, the time limit can be quite high).

    while simulating, you'll be able to interact with the circuit (and view results) via switches, leds, 7-segments displays, & other actuators/input devices, making the whole simulation very user friendly as you push a button (assignable to a keyboard's button), and activate a switch and se the circuit's reaction.

    the real strong point of such type of simulation, is that they implemented a sort of "virtual instruments", they are components (like multimeter, or oscilloscope) wich can be placed in the circuit and get theyr data updated on run-time while simulating the circuit, allowing to see the circuit's behaviour almost like you would do in real life with oscilloscopes & function generators

    those "virtual instruments" have same grafic layout & options as real counterpart, so, for example, you can change the function generator's frequency arbitrary while running the simulation at your own will, and not by a pre-defined function or table
