How to use Switches in Simulation - a Micro-Cap Tutorial #microcaptutorial

This video will be 'How to use Switches in Simulation - a Micro-Cap Tutorial'. I'll show how to use 4 different types of switches, and 3 switches will be controlled by voltage, current, or time, while the last switch will be what is referred to as an animated switch. This is where it is controlled by physically pushing the button (or actually double clicking on it). #micro-cap #microcap #microcaptutorial

If you haven't heard - you can get Micro-Cap from Spectrum-Software for free, so help spread the good news that Micro-Cap SPICE Simulation software does not any longer cost $4500, it is now Free. It is one of the best SPICE simulation programs out there. This is a limited time offer, so get your free spice simulation software today.

Spectrum-software site closed but you can find it here, and it is pretty simple and fast to make an account. Once I finally get my website up, I'll have it there as well:

Great guide again and easy to understand:-)
I have found a few functions I think is not there but could be great:
1) Duplicate one or more lines and components.
2) Group lines and components, to make it easier to work with finished sections
3) Import components into subfolders.

I should really start using this stuff.

That’s my first exposure to Micro-cap and it looks really helpful. I would love to see a video for getting started with using it. As usual, another awesome video! Thanks!

Ty for the lesson! Micro Cap is a great free resource. I ordered the Kaiweets DMM because it was on sale for prime day. Not bad at all for a meter that was under 30 bucks.

It would be useful to have a time controlled normally closed switch (a switch that opens circuit after a certain time value)

Really great software. It is possible to make some Signal Integrity with this tool?, like in QUCS :) thanks for this video

Micro-Cap version 12.2.05 now available, not sure what is new or changed

[profmatheuspinto]

Congratulations on the videos! It's helping me to understand Microcap. I have a question: how to make the values on the Y axis appear separately? When I plot a voltage and a current signal at the same time (using the probe transient), only the measurement of one of them appears on the Y-axis.

HI Eddie, another awesome great video. Thank You

[adrianvonino]

Could you explain in a future video the AC analysis in Microcap ? I understand the general concept, but i can.t seem to get how to control that thing (like, how do you tell microcap where in your circuit you wish to sweep the signal, etc.).
Thanks

Hi, I tried to simulate a capacitor charging up directly from a 1.5v battery. I used a time controlled switch to start and stop the charging, however when the switch disconnected the battery, the voltage across the capacitor immediately dropped to zero. This is not what happens with a real battery and capacitor. How do I simulate this. The idea was that I could then connect this charged capacitor to an inductor to simulate an LC tank circuit. Where am I going wrong? Thanks for posting these tutorial videos.

An animated pot would be helpful for me

Note that at least for the SPST switch, it does not work correctly in all circuits if the simulation setting is set to the Power Default, under the Global Settings Option!!! If you try to use the switch to switch resistors in and out of parallel, in the control leg of a two transistor constant current source, for example, the circuit Will Not simulate correctly!! If you simply use wires to connect the resistors in parallel it will work correctly. This behavior is in Version 12, the final release. I have not tested it in earlier versions which I will do. I have been using the previous paid versions for the last 15 years, so I will try it in MC11. Keep the simulation option to Standard Default to prevent the issue in MC12!

Tube amps!!! Let's try some sims with 300Bs !!!

For Linux users I'm glad to report that it works with wine.

I think this video would be more useful if you showed how to find this switch and what parameters to adjust. I haver a switch but dont know how to initialize it in microcap
