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

It would be hugely beneficial to be able to print/export an Ultiboard silkscreen design, where the output is a searchable PDF.

 

Currently Multisim when printed to PDF is searchable. However Ultiboard draws the text differently and therefore it does not get recognized as text in the PDF output.

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.

Since EAGLE has become so widespread many part manufacturers provide part libraries as EAGLE files downloads.

It would be really useful to be able to import these EAGLE part libraries into the Ultiboard database.

It would be nice if PDF/SVG/LaTeX PGF export of Multisim Live Graph and Circuit to include it in academic literature like papers, books...
