Hi,

Multisim Live allows for the export of .ms14 files but will not import them.

 

Multisim will not export .msjs files

 

So there is no way for the tools to be used interchangeably.  

 

This topic has been on the forum for several years(10-25-2017) so clearly there is a strong argument for not implementing it.

 

Proposal:Could you either:

  • Add MAC OS support 

OR

  • Allow Multisim Live & Multisim to work interchangeably by importing/exporting of suitable data files.

 

Thanks & regards...

 

 

 

We are a user of Multisim and Ultiboard and have been for many years.  We have appreciated that there are user fields in the data base that we can populate with our company specific information including Part Numbers and descriptions. 

 

Here is the Good idea . . . We would like to be able to have our Part Numbers display on schematics and appear in BOM reports and also transfer to Ultiboard.   Transferring to Ultiboard is important so that the Part Numbers appear on the Centroid Output.  Currently this can be done in Multisim by copying and pasting the PN into the Label field however, this a very tedious task and it leads to errors especially on large schematic designs.  As for BOM reports, it is also a very tedious task that takes a long time.  

 

With Ultiboard, this is also a manual process of copying the Part Numbers from the schematic to the Centroid output for our machine machine programs.  (SMT)  

 

This seems like these would be very useful tools for an operation who is using your software for both design and manufacturing.  Please consider adding this feature to the next update. 

Our company has used Multisim/Ultiboard for about seventeen years now.  I wouldn't know how to calculate the opportunity cost for developing our corporate library of components, but it's safe to say it has been substantial.

 

Since importing component libraries would save time, I asked NI Technical Support about importing ECAD libraries.  

 

               "Unfortunately there is nothing on the roadmap for this feature right now. ECAD is certainly a requested feature and we are interested in                    potentially working it into the product. However, there is no any plan for a soon release."

 

I recommend to anyone considering purchasing PCB CAD software to consider this.

I have worked as a contractor/consultant for many companies, many years and the number one reason there has been no demand for library of symbols, footprints, 3D models is because your potential customers have resorted to other competitors software that use Ultra Librarian. This is the first time I have ever used Multisim and Ultiboard because of that very reason which is hard to believe knowing I am a contractor/consultant.

 

At our company, Multisim and Ultiboard was recommended by an engineer who used this as an instructor at a University which is good for student education purposes only to learn how to make symbols, footprints, 3D models but in the real world… why not save time and money by using already existing libraries?

 

You should not only take note of insufficient demand… but why there is insufficient demand and why potential customers have resorted to competitors software.

Unfortunately there seems no way to upload an existing circuit design to multisim live. The only file extension accepted is .msjs. Trying to upload any .ms14 design is simply ignored (not even an error or warning is displayed)!

I posted the following in the main Multisim - Ultiboard forum but it was suggested I post it here.  Sorry for the duplicate posting.

 

Digi-key and other distributors are providing schematic symbols and footprints via Ultra Librarian in many formats (e.g. OrCad, Altium, Cadence, even Eagle!!) but NOT for Multisim or Ultiboard.  I have asked the Ultra Librarian people why this is and they say they have tools to support it but are having trouble getting required information from NI to complete the work and make a release.  

 

What does it take to get Ultra Librarian the information they need?  Who is the right NI contact?  Why do we MS/UB users not have the same tools as the other package users?  

 

Multisim is a very powerful tool and suitable for educational purposes in first courses of Engineering careers. Howevers lacks of a very simple and useful flexibility that other simulators like PSPICE or QUCS have. Is not possible to modify the variable presented in the x-axis of the Graph View!

 

If you perform a DC Sweep, AC Sweep or Parameter Sweep analysis is very easy to change the variable presented in the y-axis. However, there is not a way to modify the magnitude used for the x-axis. Thus, for example to plot the IV curve of a diode is not straightforward. In a circuit with a battery, resistor and a diode in series the user typically perform a DC sweep of the battery bias and plot the current vs the battery bias. However, is not possible to change the variable plotted in the x-axis to the voltage drop in the diode to visualize the IV (and threshold) of the diode.

 

Of course one can extract the results to an EXCEL sheet or use the IV analyzer instruments but this is not useful for educational purposes where you want to show the students similarities with the experiment performed in the breadboard of the laboratory.

In more advanced simulations sometimes the user also is interested to visualize some magnitude of the circuit vs different kind of magnitudes (voltaje, current, ...).

 

Therefore is required to have the possibility to allow the user to modify the variable of the x-axis for more flexibility of the simulations. 

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 😞

 

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

I would like the option to change the color of the PCB. This feature allows a versatile look before sending file to manufacturing.

Red, blue, purple, etc please 🙂

 

Thanks.

This is a great circuit simulator especially for those on tight budget, but 25 components seem low and really limits the usefulness to the free version. Some other web based simulators do not have this restriction and some have no limit on components at all. Please consider making the free version with less restrictions with this I suspect you would bring along more interest in NI in general.

Thank You

In instance where goal is to move a part a specific number of grid steps, it is useful to 

 

  1. select part by mouse click  Left arrow
  2. hold mouse button down
  3. press arrow key to move in direction of arrow

Ultiboard appears with Win 10 to require several pressings before the part moves one grid.  Seems that the queue for the keyboard is not flushed when left mouse button is depressed to choose part.  Or interupt does not response to first buttom push.

 

After part moves, Ultiboard accepts the next keyboard button press.  Hence, if moved say right to a location and then desire to move up.  Simply press the up arrow and instantly happens.

 

Simple request -  user interface issues of this sort make Ultiboard look like an unpolished program.  Bet fix does not take many lines of code, why not make Ultiboard super intuitive, and then a state of the art tool.

We're using Multisim 13 here at the college and I'm using it to create schematics for an engineering text. I would love the following:

 

1. Ability to export schematics in .svg (structured vector graphics) for publication quality results. Screen captures are low res and produce larger files even when reduced to b&w.

 

2. Schematic text able to use subscripts. Perhaps a special character could be used to signal this (like in TeX). For example R_f means "R" with subscripted "f". Currently, I do this with two different text boxes using different font sizes and manually align them. Very inefficient.

 

Thanks,

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.

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.

Hello to all,

 

it was cool, if we have MultiSIM 3D virtual breadboard view for myDAQ and Digilent boards like we have for the Elvis boards.

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...

Hello,

 

I am missing a functionality which is common to few other design tools.

 

Description:

 

1) Select component

2) Type on keyboard: srx 30

3) Result: Selected component is moved relatively 30 units in x direction 

 

This is very efficient way how to position components on the board. You do not have to watch coordinates and carefully = slowly operate with mouse to place component in correct position. 

 

Best regards,

Jirkus

 

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

Dear NI

 

Ideas for NI Multisim software:


1. Schematic: To make an option to lock REFDES during copying circuit to the new sheet.

 

2. Schematic: To add power bias annotation for a components.

 

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

 

4. Schematic: To add operating state annotation for transistors (active, cutt-off, saturated).

 

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). 

 

6. Simulation: To add circuit optimizer with various algorithms: Hooke and Jeeves, Levenberg-Marquardt etc.

For example: I would like to find a resitors values according to voltage limits.

 

7. Simulation: Current Worst Case simulation can not find right solution for a non monothonic functions, so please consider to add Hooke-Jeeves algorithm to find real min and max.

 

8. Simulation: To add Root Sum Squared (RSS) method.

9. Simulation: To add assymetrical tolerances option for a components (resistors, capacitors, voltage and current sources etc.)

 

10. Simulation: To add additional drift tolerance (aging, humidity etc.) option for a components (resistors and capacitors). Please create an option to turn ON and turn OFF additional drifts globally for a whole circuit design and for specific component.

 

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).

 

12. Grapher: To add histogram plots for a Monte Carlo simulation incl. table with data: MEAN, SIGMA, UCL, LCL:

 

  • Normal distribution plot
  • Cumulative distribution plot

13. Grapher: To add option to generate one report for Worst Case EVA, RSS and Monte Carlo.

 

14. Grapher: To add 3D plots (see circuit optimizer).

 

15. Interface: Batched analysis is fine, but it would be a good to see TEMP parameter visible in main window.

 

16. Interface: Fast BOM import for Excel and txt file (incl. some component parameters included value, TC1, max operating voltage and so on). For a quick changes on schematic.

 

17. Simulation: To add Worst Case option to Monte Carlo analysis to check ONLY endpoints values.

 

18. Model: To add a module that can build a component model from characteristics from datasheet (eg. to track output voltage characteristics of voltage regulator and to build behavioral model).

 

19. Model: To improve custom component drawing editor (make it handy and efficient like drawing schematic in Multisim). Current solution takes too much time.

  

The goal of these changes is to focus your product more in professional market where engineers must to find voltage/current limits according to operating temperature limits and component tolerance variation. Your product is good but it might be more oriented to perform these tasks much faster.

PB

 

This seems to have become worse and worse in recent revisions of MS and UB.  When the spreadsheet is open on a net or part tab in UB or MS every time I touch a net or part or row in the spreadsheet it redraws the screens over and over and over for many many iterations before calming down.  At least 3 times but sometimes as many as maybe 10 or more times.  And it's not very fast either.  It is becoming VERY irritating.
