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.

The following problem has been detected in Labview communication with Multisim:
When a new instance of Multisim is connected to Labview, and several operations are performed on it, the time it takes to do these operations increases progressively each time an operation is repeated. The time increases in each and every one of the operations that are performed on the open instance: measure, place components, etc ... The increase of time is significant since an operation that first time takes 0.5 seconds after several repetitions can take more than 5 seconds.
A temporary solution until you fix the problem is to close the connection with Multisim and re-instantiate a new connection.

There are certain types of semiconductors (such as thyristors) which fail to operate correctly or cause errors/crash unless specific simulation settings are chosen. The requirements for these settings are made known by NI techs after sending them the circuit (which works fine on the bench). Avoid having to go through NI tech support for these types of components to make known good designs operate correctly under simulation by adding the simulation settings criteria to a configuration file that associates the settings with the troublesome components and alerts the user to the requirement thus avoiding a negative simulation experience requiring tech support for the unsuspecting user. It could be a flag added to the model.

This is not the first time this suggestion has been forwarded to NI. The process of semiconductor component selection in Msim is BACKWARDS. Components are frequently chosen to base a design upon because they are available, the price is right, already in stock, etc. Quite frequently these parts are not found in the component library. There is no way to identify which components in the library may be used as a satisfactory replacement for simulation purposes without going back to a vendor site (NI preferred vendor obviously because those vendor's parts are what's in the NI library.....) and start a tiresome search for a compatible part and whether or not it is in the NI library. That's a ridiculous process and waste of time. This request is to expand the NI semiconductor component library databases to include key semiconductor criteria, depending on device type of course,  such as hfe & HFE, Ft, leakage, capacitance/switching time, Vsat, Vf, Vgt, Igt, Ih, It, IDSS, RDS, channel mode, Vz, Iz and so forth. There should be little difficulty obtaining this from your vendor library sources and associating a part number with it's key criteria just as the vendor does to make part selection possible.

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_3.png

 

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_4.png

 

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). 

Screenshot_5.png

 

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.

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.

Having spoken to customer support, it would be useful for Multisim to have an automated function whereby it checks if a component in a design is in the corporate database.

 

There is a function for updating components, which would bring designs from older databases or that have been created without the current corporate database to be updated. However any components that aren't in the database are simply ignored.

 

Is it possible to have the functionality to somehow point out that a component in a design is not in the database. Without having to individually go through and check?

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.

Can Multisim do a temperature sweep in DC analysis? If not, this should be added

I'd like to have an option for automatically exporting simulation results to a selected file format, including automated resampling to a desired sampling rate. This is related to this previous idea. Preferably Multisim would also automatically discard the exported results from the memory.

 

I'd like to be able to set a large number of simulations to run, possibly including a wide range of parameter combinations through the parameter sweep analysis, and have the simulations run and be automatically exported to a selected output format without user interference.

 

Due to the memory handling issue I mentioned in the post linked above, I can currently only run simulations one by one manually saving the results in between. With an automated export I could leave the computer to run the desired combinations during nighttime and have it discard the exported results from memory, allowing the next set of simulations to run.

The Idea: It would be nice to be able to set a desired sampling rate for a transient simulation before starting the simulation.

 

Background: We need to run longish transient simulations with a reasonably small TMAX. But we don't need all the intermediate time points used solely for helping the integration to converge. Multisim claims to run out of memory after occupying somewhere around 1 GB of memory, sometimes less. This is not a OS or hardware limit, but something intrinsic to Multisim's memory handling. This behavior is more bug-like than a real limitation of the software.

 

The capability for resampling/interpolating is already available through the export to .lvm files (see attached figure). Although I think the memory handling issue should be solved separately, allowing Multisim to discard irrelevant time-points on the fly would spare precious memory during more demanding simulations.

I'd like to have an option for easily copy-pasting customized SPICE options from one Active Analysis to another. Either through saving to a file and loading to the options of another analysis, or simply as a "copy settings from another analysis" button.

 

It would also be nice to have a way to collect/save known working option-sets for various types of designs, separately from the actual design files.

Dear Sir or Madam!

It would be great if there were provide support of Darlingon transitors in the next release of Multisim Online

Thank you!

When a new version is released and installed it resets all configs, preferred paths, libraries, etc. to defaults.

 

It would be far more friendly to inherent the settings from the previously installed version instead of doing this.  Almost all other app updates I get seem to be able to do this with no problem.

 

 New versions (last 14.1) can't even load the configs from the previous version, so it's left to the user to re-create them from scratch.

Add some basic Digital Logic gates and interactive digital constants to the simulator. Just basic 2 and 3-input gates would be great.

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

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).

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

 

With the 14 version release there are probes feature added that I did not have a chance to evalute however probe can be moved dynamically to the specific net to check a signal level (voltage or current) or when you place on a component so power dissipation can be measured and showed (power dissipation vs time).
