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 just finished laying out 3 boards and so I have some suggestions to make things easier in the future...


1) Add a 'net' column to the SMT Pads and THT Pads tabs, to show which net the pin is attached to.  This is documented here:

It would let me see at a glance whether certain pins are actually connected to the nets they should be connected to


2) Add the ability to click on an error circle on the board and have Ultiboard highlight the error in the spreadsheet.  It works the other way around (click on the error in the spreadsheet view and you jump to the error on the board.  But it would be nice to go in the other direction.  I had problems with vias hitting incorrect traces and the spreadsheet details exactly which traces are connected, but I wanted to work on a specific problem on the board and didn't know which spreadsheet error this corresponded to.  This happened a lot.


3) Change the highlight color in the spreadsheet.  For some reason on my computer, I can barely see when a row is highlighted in the spreadsheet.  This is the same for Multisim and Ultiboard.  The background in my spreadsheet tab is white, and the highlight color is a very light gray.  If I look at the monitor at an angle so that the light hits it just right, I could see which component was highlighted.  But my neck started to hurt after awhile.


4) Have a button to turn on/off all layers at the same time.  I had an 8 layer board, and I alternated between just looking at the layer I was routing on to looking at all layers to figure out where to drop a via.  Double-clicking on each layer got very tedious.



MS current only allows embedding of bmp graphic files.  Quit often it has memory errors with even moderate bmp file sizes, and other often fatal bugs after you've installed a couple bmp graphics.


It would be great if it could support more modern graphics file types that can preserve detail without requiring such large file sizes.


How about just supporting PNG's at least?

So far so good.

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



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.


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...

It would be helpful in more complicated designs to have an option to color nets. Currently Ultiboard offers only "Highlight net" option, but it highlights only one net, with a predefined color and disapperas after doing something else. Net coloring allows to glance and see, for example, power pins locations.

There are much more footprints of connectors available in Ultiboard than in Multisim. To create a correct circuit diagramm I need the same foortprints in Multisim. There are not enough connectors in Multisim.

It would be very helpful to have all the connectors in Multisim too!

I'd like to see a panelization option in Ultiboard, perhaps similar to the one in Altium ( Preferably with an option to panelize multiple different designs onto a single panel, choice of V-groove's / scoring, break-off tabs, etc.




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.

 Ultiboard's single interface for layout and simulation with ultiboard's new parts spice model library and all the test instuments from multisim

Set up ultiboard with all the test instruments and spice models  like multisim. You would do away with multisim and develope a single interface within ultiboard to simulate and design and layout ....

You would place the parts on the board, i.e. transformer ,diode caps wire them  like you do in multisim, place test instrument ...

This would save time because you would place parts where the are to be , have the ability to run simulation within ultiboard  single interface ..

Place a 741 op amp from the ultiboard library that would have the foot print and spice model with in ultiboard , place the feed back resistor ..



It kinda make no sense to lay out twice , once in multisim , then ultiboard , the single interface would be king..

Update Multisim Touch to take advantage of iOS 9 side-by-side multitasking features.



is it possible to do ? -

ZOOM SHEET - F7  - to apply to all active sheets and sub sheets together.



if it is not now, it would be nice to have in next revision





In Ultiboard it is possible to export a 3D IGES, but it is not possible to import these 3D IGES files in to Solid Edge or Solid Works. It would be a big improvement of Ultiboard if this was possible in the next update.



the idea is that the colors of nets in Multisim will be automatically set for different nets. For example the ground net will automatically be black, the power supply (plus) red and so on... Maybe there is a way to save the user's preference in a config-file?


Thanks a lot


By default the soldermask Top and Bottom for a troughhole Via in Ultiboard are checked. It would be nice if I could select in the global preferences or PCB proberties of Ultiboard what I want for default for all the via's I place on the design.

Now, when my design is ready I have to think that I should uncheck the soldermask Top and Bottom of all via's on the design and when I did that and place a via the soldermask for this new placed via is checked for Top and Bottom.

I am a university lexcturer and have  alarge number of Multisim 14 files that I use in teaching. I try to encourage students to install Mutisim on their own computers (it is available under our site licence), but most are not happy to do this for many reason including different OSes, lack of disk space etc. etc. . However, Multisim Live is the answer - but i need to be able to transfer my design across to it.


It would also be useful for me personally as I use a Mac for most things and have to revert to a PC for MS 14 Smiley Sad


Please add an import function - you already have an export function

I am using Multisim 14 with the BASYS3 board  to teach a beginning digital class.  It would be very useful to have a searchable document reference of the available PLD components.  The best way I see to get information now is to do a internet search on each individual name.  Are there any better sources?  Thanks so much for your help.

It's possible to select, edit, and place a net bridge footprint in Ultiboard (that connect two different nets, such as analog and digital ground), but there is presently no way to create a net bridge component in Multisim to complete a schematic that exactly matches and forward annotates to a desired board layout.  At least some other software packages (e.g. Altium) do offer such a component.  The ability to create such a part in Multisim would make for a much cleaner process, including design verification.

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.
