Hi, i am a inventer building and winding my own coils

since your program is perfect for testing differant windings i have a few things i want you to add

 

multilayers sow for instand a 4 layer transformer

select with type of wire and the gauge witch automaticty calculates the ohms

the shape of the coil turoid or tesla coil like

the core itself, i would like an option to use a micrometalmix core or an aircore

 

thanks in advance

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.

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.

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.

 

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

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.

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

 

 

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.

Instead of identifying errors by double clicking on the Yellow X of entry in DRC Tab of spread sheet, double click on the error circle marker in the workspace to automatically point to the error in the list under the DRC Tab.

 

Sounds simple, should be easy to add feature.

 

This way all errors associated with a section of the layout can be systematically fixed.

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.

 
 
 

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 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.

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

UB differential pair groups should be able to specify how close to equal length is required.

 

There is almost always some amount of length matching error.  Not being able to specify allowed error means you will always get a DRC when you have matched length nets.

 Ultiboard's single interface for layout and simulation with ultiboard's new parts spice model library and all the test instuments from multisim
Status: New

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

There are much more footprints of connectors available in Ultiboard than in Multisim. To create a correct circuit diagramm I need the same foortprints in Multisim. There are not enough connectors in Multisim.

It would be very helpful to have all the connectors in Multisim too!

The only way to do a horizontal cylinder is a resistor body between pins.  Often other configurations of horizontal cylinders are needed.  i.e. tubular radial resistor that lays over on it's side, some relay bodies, and various mechanical objects that don't have axial electrical pins. 

 

I've had to resort to horizontal rectangles to do this, which does not convey the image very accurately.

Since netnames, power supply names and sheet connector names are not actually parts there is no conflict for naming a refdes the same as one of these.  I believe this used to be OK in some previous version of MS.

 

This would be very useful for test point parts.

 

Does anyone even read these ideas?
