I'd like to have an option for easily copy-pasting customized SPICE options from one Active Analysis to another. Either through saving to a file and loading to the options of another analysis, or simply as a "copy settings from another analysis" button.

 

It would also be nice to have a way to collect/save known working option-sets for various types of designs, separately from the actual design files.

 

1. Increase Width of all traces together in the grapher.

2. Option to choose axis variables in the grapher, for example instead of time in the x-axis, I need some circuit voltage, for this option the simulator should simulate for all circuit variables, and after completion of simulation, the user could change the axis variables as desired. ( In PSPICE it happens the same way, and its useful)

3. When inductors are coupled using Inductor Coupling Block, then those inductors should be assigned dot polarity, same should also be done for the transformer models.

4. When I perform Transient, DC Sweep or Parameter Sweep analysis, all the selected output variables are plotted on the same graph, this is good for most of the times,
but sometimes I desire them to be plotted on 'Different Graph but on Same Graph Page' and I know this can be done by copying the original graph and paste it on the same page and then deselect the unwanted variables, which is tedious work. So there should be an additonal option to plot the variables on 'Different Graph but on Same Graph Page'. Also user should be able to change the bottom axis range of all graph together for easy comparision.

5. Is it possible to incoporate the datasheet of components within the multisim, without visiting manufacturer's webpage?

6. I desire the multisim to create backup of all custom setting made to it (for example Keyboard Shorcuts), so that I could restore it in case of new installation.

7. Multisim Viewer for viewing the schematics and simulating them

I am using Multim Touch form the applestore and I am very satisfied. But...

How about a Pro version of Multisim Touch with a price tag around 30.0 U$S but with more capabilities

like being able to use self-defined models, having some more components form the beginnig and being able

to exchange files (like models for instance) over iTunes in the App section.

I think educators and hobbyst would most likely be very inetersted.

There are certain types of semiconductors (such as thyristors) which fail to operate correctly or cause errors/crash unless specific simulation settings are chosen. The requirements for these settings are made known by NI techs after sending them the circuit (which works fine on the bench). Avoid having to go through NI tech support for these types of components to make known good designs operate correctly under simulation by adding the simulation settings criteria to a configuration file that associates the settings with the troublesome components and alerts the user to the requirement thus avoiding a negative simulation experience requiring tech support for the unsuspecting user. It could be a flag added to the model.

Can Multisim do a temperature sweep in DC analysis? If not, this should be added

I'd like to have an option for automatically exporting simulation results to a selected file format, including automated resampling to a desired sampling rate. This is related to this previous idea. Preferably Multisim would also automatically discard the exported results from the memory.

 

I'd like to be able to set a large number of simulations to run, possibly including a wide range of parameter combinations through the parameter sweep analysis, and have the simulations run and be automatically exported to a selected output format without user interference.

 

Due to the memory handling issue I mentioned in the post linked above, I can currently only run simulations one by one manually saving the results in between. With an automated export I could leave the computer to run the desired combinations during nighttime and have it discard the exported results from memory, allowing the next set of simulations to run.

The Idea: It would be nice to be able to set a desired sampling rate for a transient simulation before starting the simulation.

 

Background: We need to run longish transient simulations with a reasonably small TMAX. But we don't need all the intermediate time points used solely for helping the integration to converge. Multisim claims to run out of memory after occupying somewhere around 1 GB of memory, sometimes less. This is not a OS or hardware limit, but something intrinsic to Multisim's memory handling. This behavior is more bug-like than a real limitation of the software.

 

The capability for resampling/interpolating is already available through the export to .lvm files (see attached figure). Although I think the memory handling issue should be solved separately, allowing Multisim to discard irrelevant time-points on the fly would spare precious memory during more demanding simulations.

Dear Sir or Madam!

It would be great if there were provide support of Darlingon transitors in the next release of Multisim Online

Thank you!

5. Schematic: To set some min and max limits for a voltage, current or power (they shall be visible in Grapher when you generate the plot).

3. Schematic: To add active probe (see CircuitMaker 2000 solution).

 

With the 14 version release there are probes feature added that I did not have a chance to evalute however probe can be moved dynamically to the specific net to check a signal level (voltage or current) or when you place on a component so power dissipation can be measured and showed (power dissipation vs time).

11. Simulation: To add component stress analysis but more advanced. The goal is to check maximum dissipated power according to derating power characteristics for resistors according to current operating temperature (TEMP parameter for circuit simulation) and maximum voltage for a components (resistors, capacitors).
