This would make managing files in a project that much simpler.  As it is now you have to go into windows explorer, rename the file, go back to the toolbox, click on the file, navigate to and select the new file after it tells you it can't find the file anymore.


Just a right click/rename would be so much smoother.

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.

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.

New feature proposal:


Frustrating is the number of button pushes necessary to see a net on multiple sheets/




Net appears on two sheets


currently have to select sheet to see net.  To see on next sheet have to select sheet.


Selecting takes time.


Would be great if   after selecting the RED arrow, that space bar would go to next sheet to see net.


Sounds trivial, Upverter shows how they have done this, and then in Altium, one of the so called top csd tools, their tool requires one third mouse clicks.  They even have people in house analyzing how to reduce clicks to help user to save time.


Ultiboard could have this feature and be the premier Circuit Design Suite.



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.

 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..

Good day

Can you please add these important components in Multisim 14 as I consider thm extremely important. MAX1978 is a smallest safest most accurate single temperature controller for Peltier Thermoelectric cooler while MC10EP05 is an ideal pulse shaper where duty cycle skew is critical.

I would like to know how soon can this be done. I am on a extremely tight timeline.


Please help.


On a good day, can select net in Multisim Transfer and will be identified in Ultiboard.


Sometimes it is difficult to see the net/trace


Ultiboard needs a zoom in function to be able to see the net trace


Ultiboard also needs to highlight in spread sheet the net without having to click on net, and go to results


Goal efficiency, too many button pushes to see in spread sheet.


Also, TRANSFER  > highlight just does not work.  Have a look at Upverter, down load program and convince yourself.  There when net is highlighted since schematic and layout are in single environment the net/trace is highlighted, no extra clicks.  Ultiboard needs to be cleaned up, rid of legacy style methods.


Most designers need to find nets in ratsnest many times during the day.  Ultiboard if it is to be considered a PRO product needs automatic identification with out highlight or cross probing in multiple steps.


Multsim find NET works great, again goes to results and should just identify in workspace, and have a key to go to the next of the search results.


Every other layout program has an alphanumeric Find function.


Ultiboard, get with the program.

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.

Often different types of prints are needed.  It should be easy to provide for saving and re-loading a print config as needed.


Export config schemes have already been implemented, which was a big plus.  Similar for printing would be great.


A bonus would be if it also remembered and set the printer properties for the target printer!



It's a pain switching everything back and forth between metric and imperial, and changing grids for fine detail parts. 


Providing for saving and loading grid and unit configs in UB should be pretty easy to do.

Sometimes a part wants non-solder mask defined pads with a certain amount of clearance, but I have only seen an option in Ultiboard to expand solder mask openings globally, and not by part.


It would be nice to control this on a part by part (or footprint by footprint) basis.


If encrypted models were supported more vendors might be willing to release their models for general use.  I've heard quite often from vendors that they don't give out good models because they don't want to make it easier for someone to reverse engineer their parts.


See LTspice for example.  It would be great if MS could support LT encrypted models. As it is now I usually have to go back to LTspice to simulate LT devices.


TI also releases encrypted PSPICE models for many of their parts.


This would be great for their switching regulator models.  I'd much rather use MS to simulate, as the interface is much more modern (not like an MSDOS app from 1990).  It would also save some duplication of work.

Update Multisim Touch to take advantage of iOS 9 side-by-side multitasking features.

Hello, thanks for response


There is something about MS wire color scheme


Technically there are a lot of colors and tints available but practically to distinguish there are no more than 7 or 8 colors.

My suggestion is to use 2 color scheme – 1 color for wire and 2nd for strip.

In this case wire would be clearly visible with from 7*7 to 8*8 color combinations



with hope it helps

thanks a lot




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





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.




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!
