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.

 

Cheers

i am looking forward to see sensors and transducers in Multisim, for example models of thermocouples, NTC and PTC , LDR, even ultrasonic sensors  and LVDT can be easily added to Multisim. 

also i am waiting to improve the microphone model so that we can use it immediately in the circuit.  Further more, we are looking forward to Arduino in multisim.

 

regards

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 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.

 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.

Hello 

 

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

 

thanks

Here is my circuit. Be default max value of time scale is 10 mSeconds. I tried to change to 50 mSeconds, but keep reverting to 10 mSeconds. Is there a workaround?

I have been using Multisim for a long time, but I designed the PCB in another software. I recently decided to give Utilboard a try because I didn't feel like redrawing the circuit. I exported the schematic to Utilboard and it looked good in 3D. I published a printed circuit board and people wrote to me that one wire was missing. I checked the circuit, everything was ok, but the PCB was missing a wire. I can send the ms14 file.

Hi, 

 

It is an exhausting enough experience importing netlist files from colleges who do not use NI. But why NI does not take the time and some effort to provide an export file option to make the analyzed circuit data MATLAB ready?!

This way, I can recover some of the time the lost setting up the project (almost from scratch) on Simulink, and and complete their task on MATLAB without, additional overhead.   

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.

Utiboard has some windows and fields to create net, buses and component groups in the "Group Editor" tool. The bus groups are required if you want to autoroute a particular bus. However, there's no creation of a bus group when you create a bus in Multisim, so this have to be done manually in Ultiboard, and the back annotate it to Multisim. So I think that is a good idea to have the same "Group Editor" window in Multisim, and also automtically add Buses to Bus Groups. Also, another related enhancement could be the creation of component's "Room Property" (like OrCAD) for components that need to be near in the PCB as passive components for medium to high speed IC's, and use this property to automatically create a component group, and also aid Autorouters to impose particular constraints for this group, like trace length, impedance, and maximum via count. This can increase success and speed of ultiboard Autorouter, or make manual placing and routing much faster.

I have been looking for a way of creating sub-circuits, i.e., modular designs. If this does not exist, it would be nice to have it in MultisimLive. 

 

 

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.
