Hi, I'm hoping that someone will know the answer to this question regarding the simulation speed on multisim 8. This is a great simulation tool for electronics but it has one major drawback – the documentation doesn't seem to cover everything, or if it does then it is in too much detail.
What I am trying to do is run the simulation in realtime. The software is great for "slow speed" where a circuit can be diagnosed but what happens if you want to see the circuit run as if it has been built in real life?
Looking at the settings, I can see that you can change the maximum time the simulation runs for and limit the maximum step that can be taken, but there is nothing that I can find that indicates the speed at which the simulation is to be run at.
Any help is greatly appreciated.
Kind regards

You'll have to explain more. You don't need the simulation to run in real time. For example:
Lets say I build a circuit in the simulator that also conatins a button pressed by the user which, activates some function. In real life the button press might not occur for many seconds. All I would need to do is simulate the button press happeing at say a time of 3 seconds. Setup the simulator to run for 4 seconds. Now when it simulates this, it wont take 4 seconds - that depends on step size _AND_ what the circuit is doing. If I simulate with a step size of 1 second - it will still be finished in much less than 1 second (if the circuit has no dynamics happening faster than this).
BUT the final simulation result will be time-accurate.
You see, you have to understand, the simulator is solving circuit equations not showing you real time response- for 99% of the time we dont want real time response anyways! That takes too long.
I see no need for any circuits high speed or low speed that require a real time simulation. Why is it you think you need it to be?
