Hi,

 

I am a lecturer at UNED, the Spanish National Distance Learning University. It is a University offering blended learning, however, the online learning is essential. I am member of a team composed of 3 lecturers, who are teaching Digital Electronics to first years' students in a Computer Science Engineering BSc programme. More than 1300 students are enrolled in our module this year.

Multisim live is a great innitiative, thank you for that. There are some components we are still missing in the live version as for Digital Electronics, but we understand that this is an evolving project that will grow gradually.

 

Another issue for us is that, among our students, we have an increasing rate of students with disabilities, including people with visual impairments and people with impairments in the mobility of upper limbs. For that reason, multisim live's compliance with WCAG 2.1 is essential for an inclusive university like ours.

 

We are already working with accessible mathematical expressions, and with tactile diagrams of theoretical concepts.

 

Any improvements of an outstanding practical tool like Multisim in that direction would be really highly appreciated. Not only by our university, I believe. Attending the needs of disabled students is currently mandatory according to the laws in Spain and in many other countries.

 

Kind regards,

Alejandro

 

This simulator is very good. My entire class is using this simulator for my practical purpose. But some components are missing like :-

1.) Square wave 

2.) 7 segment display

3.) 7 segment display with decimal

 

Please add these components it will be highly helpful.

Thankyou. 

Sometimes in schematic we have to show high current and low current paths. So options to make some track wider and thicker , this for representation only.

Many other software have this feature.  Make life easy.

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. 

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. 

Possibility to connect a relay and a contact related to the relay in the circuit diagram with the name of the relay.

I've recently switched from using RS Design Spark to the NI Circuit Design Suite. In Design Spark, I used component models from componentsearchengine.com and imported them using a piece of software called Library Loader by SamecSys.


I was more than a little disappointed to learn that NI Multisim/Ultiboard is one of the few EDA's with which it is not compatible, and it's made me question whether switching to Multisim was the right choice for me.


I've contacted SamecSys to ask if there are any plans for compatibility with Multisim, and had a reply from Mark saying that he would love to make Library Loader compatible with Multisim/Ultiboard. He is ready to go with the project, but requires the co-operation of NI.

 

I've also contacted NI Technical Support and received the following response:

 

The best way for you to further this issue would be for yourself to post on the MultiSim/Ultiboard Ideas board which allows for our R&D department to see the requests of our customers. I believe a few people may have already posted about this issue but the more people that post the more likely it is for the issue to get raised!

 

I'm posting this request here in hope that it is seen by the right person.

 

Mark at SamecSys is ready to get to work with making Library Loader compatible with Multisim, he's just waiting for somebody at NI to get in touch with him and co-operate.

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.

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...

 

 

 

The gerber output from Ultiboard should have either an option to turn off the targeting and cornering or just leave these out.  These were used back in the cave man days to line up the gerbers for a photo shoot.  Today, they are useless and make more work in deleting them on each layer.

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. 

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.

Add the possibility to transfer components user fields from MS (MultiSim) to UB (UltiBoard) in TEXT variables (TEXT,TEXT1,TEXT2,...).

In UB add the possibility to have the component height (height + Offset) and user fields to the part centroids export

In UB add the possibility to export user fields in the BOM

On upgrade it would be interesting to automatically keep the circuit designer suite configuration, particuliarly for customized interface, user button and keyboard shortcuts.

 

Thanks

It would be interesting to have a feature to import either text base, .csv, or XML format netlist into Multisim. We have a Flying probe machine (Acculogic brand) that export netlist in XML format (See the attached file) Would it be possible to add the feature added to import that netlist in Multisim. See the attached xml file to see an partial example of netlist that we have.
