How long does a simulation take?

For a case running on Multisim, how can I get the information about the CPU running time? Of course, more accurate, better.

Hello,

Just to clarify, you would like some information about the CPU resources being used while simulation is running.  This will depend on numerous factors including how much RAM you have, how complex the circuit is, and how big the circuit is.

To find out this information you can check the Task Manager.

Hope this helps!

Actually, I just want to know how long it takes. I know it depends on the computer and circuit complex. But it should be more accurate than my watch because most cases can be finished in 2 seconds. Some Spice can provide a log file when a simulation is completed with the running time included. Does Multisim give this information?

Hello,

At the lower right-hand corner of the Multisim screen you will be able to see how long the simulation has been running for.

This is the information the Multisim provides.

Thank you for your reply.

But this is not exactly what I expected. I think you mean interactive simulation. I am interested in "Transient Analysis" by setting "End time". After the simulation is started, it can run without stops until the end time arrives. For example, "End time" is 8000 seconds and the whole simulation finished in a very short time( for example, 1.23 seconds). How can I find the real elapsed time (1.23 s)? Does Multisim give this? Thanks again.

This is something that is currently not a feature in Multisim.  There is a Corrective Action Report in place, for this to be looked at.

Thank you for your feedback!

I am new to the Multisim ver. 13 and learning the product. I used the tutorial and designed a circuit that is a small analog signal. amplies it and then counts the cycles on a simple digital counter. I run the simulation after 4-hour and still was running. I sensed something is not right and stop the simulation. The question is, how long the tutorial designed simulation suppoedly takes? Thank you
