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. 

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

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.

 

 

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 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.

It would be nice if the mask would show up in the 3D view of the board.  This would greatly help prevent forgotten or misplaced soldier mask areas when looking at the board in 3D.

Current version of Multisim doesn't allow to view the Fourier Analysis Magnitudes in the form of Histogram. I hope it does in upcoming version.
