• Multisim scroll buttons do not work

  MS 11.0.2 (11.0.775) 17 May 2011

  Home Premium Vista 64

  Hi, I'm new to the forum and Multisim, so forgive me if this problem has been answered before (none of the search results).

  The horizontal and vertical scroll bars normal Windows are missing.

  In the lower right corner of the screen, just below the working window are two buttons with the left and right arrows. ToolTips for labels these "Scroll left" and "Right Scroll."

  When I click on these buttons, they appear "depressed" but nothing happens. This is true if I Zoom in to a small part of the schema.

  How do these buttons?

  I believe I do not have the horizontal and vertical scroll bars extremely annoying and quite specific Windows CAD program. I am familiar with several other programs layout of PCB/schematic capture (as well as several CAD programs) and it is the only program I've seen that has no scroll bars. Is there a way to turn them on?

  Now if I want to move the view horizontally in another part of the scheme I have to 'Zoom Fit To Page' and then 'Zoom to the selected area. It is extremely annoying.

  Fernando,

  Who did the trick! I now have scrollbars on pages when I Zoom to see a small part of a page.

  Thank you!

  I worked through the tutorials and the program seems to be pretty easy to use. I've been designing PC boards for 30 years and more, so I know what I want to do. Whenever I use a new program, the problem is to find how to get the program to do what I want to do. So far, Multisim and Ultiboard were pretty easy to adapt to the.

• Mod 10 down back to 8 and does not pass 7

  Can someone move this to the forum of Multisim? I can only put in Circuit Design Suite.

  In any case, I have problems with Multisim. I made more complex circuits, but somehow, I lost my memory and cannot remember it clearly. So I go on Digital Electronics 1, I'm ready for Digital Electronics 2.

  I am a 15 low meter mod. To happen 15 to 0 easily, but I want him to be 9-0, then the display shows 9, 8, 7, 6, 5, 4, 3, 2, 1, 0 and 'LOAD' then 9 and countdown again.

  Without the charge, he would go 15 - 0 and reset.

  So in class, we learned at 15 (1 1 1 1) NAND to load presets ABCD, I used a switch is customizable. I use 1001 for 9-0, but he is always put back to zero (load) to 7... So there are 9, 8, 9, 8, 9, 8, 9, 8 and so on.

  It will count down to 0 and go back to 15, but at 15 he flip 1111 to a low and will activate the load and given to 9. I can't get it past 8. I can move the ABCD to 6, and it works perfectly. It will go from 6 to 0 and then load back to 6 and repeat. When I try from 9 to 0, it just will not work.

  Any idea? Someone asked me (since I took the Multisim from Digital Electronics 1 section and he took the model section) if it must use the DIP switches and how the teacher said no cause of bounceback? She also told my partner to use only one... but I don't remember if it was instead of the clock, OR switches. I see people on Multisim using buttons instead of my switch. What is the problem?

  In addition, my display 7 segments will not work correctly.

  So, my teacher asked me what was the model number for the NAND and I didn't.

  She told me to Google the model number and then use in Multisim.

  I've done that I have placed a NAND4 - not a 7420N.

  I knew that the NAND dirtied with the count of 9-0. So, we replaced by a 7420N and there are now 9-0.

  To display, I did it properly and did so my classmates - but the default is 7446 somehow does not work and shows the numbers in front of what he has. So ONE looks like a three backward, because it lights the LED must be off.

  So we fixed it by replacing the component with a 7447.

  If I would have stuck with my instincts and tried to replace it with a 7447, I would have done this a week ago. However, the document specified using a 7446, LAB so I don't think it was a problem.

  To someone else as the question with a MOD 10 countdown with a NAND4, use a 7420N in replacement of the NAND4.

  It is fixed.

• HP and/or Techtronix Multisim and GRAPHER

  Is there anyway to have the results of the Tecktronix and the HP o-scopes in Multisim appear in the Grapher?  Not sure why they don't, but they do not.

  Hello

  Impossible to Multisim to connect directly with third-party tools and import signals from the scopes in Multisim. If you are able to get information on the scope and create a file .csv with this information, you can import this file in Multisim.

  I got this from another forum.

  "The Piecewise linear (PWL) source accepts data as the voltage or current time. You can find this part by selecting site > component, go to the group 'Sources' then select 'Sources of voltage Signal '. Place this part on the working area, double-click it and there should be an option to open a .txt file.

• Anyone has a balun for multisim spice model?

  Why is there no balun in the component library?

  Thank you, if you have a.

  David B

  dbur,

  A balun is essentially a specialized transformer model.   As a good un bon resume summary of these types of baluns, please see this link:

  http://www.Minicircuits.com/pages/BalunApplicationNote.htm

  Since you can create an ideal transformer simply using sources controlled, attached is a balun 'Ruthroff' ideal, created from 2 ideal transformers (so it works in both directions) using the same technique.

  Using the modellers of Multisim (in Multisim PowerPro) or by creating these transformers with realistic values, it is possible to create SPICE balun transformer models ' real' models.   There are several previous messages which discussed the creation of models of processor to help you.

• Multisim ttl clock oscillator library

  Is there a library of quartz oscillators ttl available for 9 Multisim?

  Hi Jk,

  Multisim has a database of Quartz Oscillators, so you will need to build you own model.  Here an example document that speaks to build oscillators:

• Several weird, sudden problems in Multisim, Ultiboard interface

  I have several sudden problems that arose when trying to review a design that changed, I worked on a couple of months ago.

  Multisim 10.0.343 strangeness:

  1. by clicking on a Multisim, Multisim project file opening, but the project file does not open. By clicking on 'Open' Multisim has the same effect. If I manually open the circuit, the entire project opens as well.

  2. I can no longer double click on a component and change the footprint; the button "Replace" is also disabled. I can always change the footpring of spreadsheet view.

  3. the icons for the placement of the pieces have changed to blue squares with black patterns (from grey buttons with color schemes).

  4. multiple drop-down menus in the top bar disappeared ('reports' is the only one that comes to mind, but the list is significantly smaller).

  5 ' transfer' menu has only one option - transfer to Ultiboard 10. There is no rear annotation or annotation.

  6. Select 'Transfer to Ultiboard 10' open the splash screen for Ultiboard and gives me the option to choose a file name, but nothing opens after that. There is no blocking or error - just nothing opens.

  On a separate note: the last time I did a major revision of this circuit, I changed a lot of net names. NET names, however, has not changed; for example, I renamed a node 'Gsyn' to 'Gs '. The 'Gs' appears in the worksheet view and the properties of the net, but 'Gsyn' always appears on the diagram and is not suppressible.

  Ultiboard 10.0.1 strangeness:

  1. the renumbering of the components in the design menu translates into a sort of re-assignment pad, causing many connection errors.

  2. same mistake earlier in the forums without response: after before annotate Multisim earlier, the list of included changes 'edit the existing component XX' for each component in the design, regardless of whether the component has been modified or not.

  3 when you place a trace which is too close to other tracks by my rules of design, I sometimes get advice 'cannot create (1) drop of water ". The program is then suspended until I click on something other than Ultiboard (show Desktop, switch to another program, etc.) When I go back to Ultiboard, the program of the United-grip Nations - but then it works super slowly, no display of updates for a few seconds and zoom in and out in pieces. I have to close and reopen the file to continue working.

  Any help would be appreciated - I'm on a deadline, and both programs are more or less completely unusable now.

  Hello

  Please take a look at the following knowledge base to resolve the issue of Multisim:

  Making gray out

  Reset the User Interface

  It is difficult to tell what is the problem with the annotation to the front without looking at the Multisim and Ultiboard files. If you can, please create a service request to ni.com/ask and send us the files.

  1. When you annotate forward, the PIN does not change is the imprint that has changed.  If the footprint currently on the design before annotate before is different from the PIN that is in your library, when you transfer annotate, Ultiboard will update the fingerprint with that of your database, this may explain what you see.

  2. you need to compare the fingerprint in your schema with what is on the printed circuit, if the fingerprint matches, Ultiboard will get what is on the circuit board to the wide and place a new there.  Take a look at the knowledge base of Unplaced Pieces after annotate with impatience , he can explain what you see.

  3 turn off the tear drop feature (Options > preferences > PCB design) and carry your board without this feature, once you completed the Board of Directors of routing, add the tear drops (design > add teardrops).

• Multisim connectivity Kit

  Hello

  I have search the Forum, but found no useful information,

  I'll start with the technical characteristics of my system:

  2011 LabVIEW, multisim 12 power pro.

  My problem:

  I tried to simulate BUCK CONVERTER with labview using the connectivity - Multisim Toolkit,

  My circuit have two entrances: the first is 3 [v] wine and the second PWM of 74% DC, 5 [v] Amplitude and frequency 200 KHz.

  by the analysis of the circuit (in theory and actual test - multisim and real circuit) I should get 1.7 output [v] - exit to start from scratch and stabilize on 1.7 [v].

  I connected successfully multisim and labview, my early exit form 0 (as was intended) and go until approximately 2.2 [v] and not 1.7 [v] as it should.

  My questions are:

  1. how can I fix the program (if it is a an error in my code) that my output will stabilize on 1.7 [v] (as appropriate) and not 2.2 [v]?

  2 there that advice on how to optimize the code (all information will be welcome)?

  P.S.

  The multisim file created in multisim 12, but has been saved as version 10 (for the reason to know)

  Hi sokal,.

  I looked into the issue and mark the reason you see the value as being about 2.2V is because there seems to be an increase in tension in the simulation round the 1 s. change the duration of simulation to 0.8 and you will see the desired voltage level.

  I hope this helps.
