Sugestion to cerate a selector in Digital

[jacneves]

version: v0.31

Quite recently, I had the problem of creating a circuit with a manual selector, with wires, with 1 input and a manually selected output,.
Is that possible, in a simple way with the Digital sw

Sincerely

JACNeves

Can't you use a switch? Switches can be toggled by clicking them when the simulation is running.

No. It as only 2 states. I need a selector to connect with 1 input line, and several outputs, where the selection is made by the uset, to connect (p. ex.) one point to another. A quinta, 16/01/2025, 17:49, Kuba Sunderland-Ober ***@***.***> escreveu:

Like this or this then? (using a Multiplexer)

[jacneves]

Look at the schematic. It helps. [image: imagem.png] Kuba Sunderland-Ober ***@***.***> escreveu (quinta, 16/01/2025 à(s) 17:49):

I have made it with a input of 2 bits, plus a decoder + a set of AND gates, between the signal and the selected line. But it becomes complex for some teaching. I will try with a MUX. Thank you Mats Engstrom ***@***.***> escreveu (quinta, 16/01/2025 à(s) 19:39):

Ok. So basically switch but with more positions than 2?I can extend the switch to allow an arbitrary number of positions. 16. jan. 2025 kl. 8:39 pm skrev jacneves ***@***.***>: Look at the schematic.

Hi, And thank you for the reply. Yes, I beleive it could be very helpfull. I used a Mux and it worked well, but a multiple switch would add flexibility. Thanks A quinta, 16/01/2025, 21:46, Kuba Sunderland-Ober ***@***.***> escreveu:

Another point worth mentioning: Since switches are real bidirectional connections that are established and disconnected while the simulation is running, they are very slow. The same applies to relays and transistors. Therefore, these components should not be used excessively.

[jacneves]

Yes, I agree. One point that I have noticed, because I use the sw for teaching, is that, when manually controled by the user, the clovk introduces longer impulses, than expected. Can that issue be solved? JACN A sábado, 18/01/2025, 17:23, Helmut Neemann ***@***.***> escreveu:

@jacneves
The graph has no running time. This would make little sense, especially if components are controlled manually. Therefore, the graph records changes. You can imagine it as if the time in the graph is stopped until the next change is made. If a clock is then running and a manual change is made at the same time, it appears as if the clock pulse is twice as long.
