Some users have suggested the following ideas:

1) Add a feature searching functionality: The current search options are mostly related to the vendor name or characteristics, sometimes it could be cumbersome to find a part using the vendor name. Parts should be also accessible by its characteristics and features.

2) Add a command to access via command line the interactive simulation.

More and more PCB fab vendors are asking for OBD++ output.  Eventually I think you are going to have to support it.

When I perform any 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 separate graph (but on same graph page) for easy comparison 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.

 

In the screen-shots,

Screenshot_3: What multisim does by default - Plotted all the variables on same graph (which is good most of the times!)

Screenshot_4: I manually separated the plots by copy-paste the graph on same graph page and deselect the unwanted variables, looks good! (but tedious)

Screenshot_5: Disadvantage is - If you zoom in to one graph, the same won't be affected on the other two, one way is to manually copy the graph properties and paste in onto other, but again you will also end up in having same variable selected (red one).

All together it will be a tedious task if one has to plot many such graph and use zoom feature regularly.

 

So I request the NI team to provide an additional option to plot the variables on separate graphs on the same graph page. User should be able to change the bottom axis range of all graph simultaneously for easy comparison and zoom feature must work for all the graphs simultaneously. Also provide same cursor for all the graph plots.

 

 

When a new version is released and installed it resets all configs, preferred paths, libraries, etc. to defaults.

 

It would be far more friendly to inherent the settings from the previously installed version instead of doing this.  Almost all other app updates I get seem to be able to do this with no problem.

 

 New versions (last 14.1) can't even load the configs from the previous version, so it's left to the user to re-create them from scratch.

 

 

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...

UB differential pair groups should be able to specify how close to equal length is required.

 

There is almost always some amount of length matching error.  Not being able to specify allowed error means you will always get a DRC when you have matched length nets.

Instead of identifying errors by double clicking on the Yellow X of entry in DRC Tab of spread sheet, double click on the error circle marker in the workspace to automatically point to the error in the list under the DRC Tab.

 

Sounds simple, should be easy to add feature.

 

This way all errors associated with a section of the layout can be systematically fixed.

Currently, there is no way the save/export the paths under Options>Global Options to another computer. It will be useful to export the settings and paths of a certain setup more easily to have, for example, all the computers on a teaching Lab with the same Settings.

Exporting on as .png file is limiting in the sense that you actually have to crop the exported figure to have it fit nicely in a word document. Scaling of the figure also leads to a loss of quality. The grid in the background should also be removed on request.

 

As Microsoft word is largely used to create documents for students, the possibility to export as metafile would be useful to teachers.

 

p.s. Word does not fully support svg files but "export as .svg" would still be a nice option.

Hi, this is Dr.R.Senthilkumar, Assistant Professor, Department of Electronics and Communication Engineering, Institute of Road and Transport Technology, Erode, INDIA.

 

Here I wish to share my circuits designed for analog and digital circuit experiments.

Hello,

 

Recently, a Monte Carlo Simulation was run, testing and changing the value of 12 resistors on a simple circuit. But the computer crashed rounding the 8k samples stating the error:

 

 

SR-3310283 - Multisim error.png

Changes on the resistors, power sources and simulations options were made but still, the tool was not able to handle at least 20k samples on the same run. The computer used had 40 cores and 64GB of RAM.

 

It will be a great improvement to the tool if the memory could be increased or even creating a 64-bit application.

 

Thanks.

 

Are there any plans to offer dark mode in Multisim Live Grapher ?
Dark mode presentation mode is more pleasant. 

Hello everyone

It would be great if we could add a dummy object. I mean a schematic element that represents only the footprint. There are so many items that are not in your library. It seems a good idea if I could select a "DIP14" entry without a simulator behind it.
Only to be able to create a simple schematic...

Hi, i am a inventer building and winding my own coils

since your program is perfect for testing differant windings i have a few things i want you to add

 

multilayers sow for instand a 4 layer transformer

select with type of wire and the gauge witch automaticty calculates the ohms

the shape of the coil turoid or tesla coil like

the core itself, i would like an option to use a micrometalmix core or an aircore

 

thanks in advance

The only way to do a horizontal cylinder is a resistor body between pins.  Often other configurations of horizontal cylinders are needed.  i.e. tubular radial resistor that lays over on it's side, some relay bodies, and various mechanical objects that don't have axial electrical pins. 

 

I've had to resort to horizontal rectangles to do this, which does not convey the image very accurately.

Since netnames, power supply names and sheet connector names are not actually parts there is no conflict for naming a refdes the same as one of these.  I believe this used to be OK in some previous version of MS.

 

This would be very useful for test point parts.

 

Does anyone even read these ideas?

 

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

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.

So far so good.

It would be awesome if Multisim Live included also the Multimeter feature, as the PC software.
