• creation of component custom Multisim version 12

  Hi guys,.

  So I am a student with a project I have to simulate on multisim. It is not part of the project, but the project has over 100 components inside so I started to wonder if I could make my own components with the circuits inside of them.

  So ive trying to do a custom of my smaller circuit component to test if it works and race dramas.

  The circuit is a code of grey 8-bit binary code converter.

  If I had done the converter and put connections HB/SC on the inputs and outputs.

  Then registered as a netlist cir file.

  I then opened in Notepad, added

  . SUBCKT G2B_8BIT G0 G1 G2 G3 G4 G5 G6 G7 B7 B6 B5 B4 B3 B2 B1 B0

  up, so my component is G2B_8BIT, and these are the names of the 16 pins

  I then added. ENDS at the end

  I haven't added any mapping of pine because it is only a simulation need not print

  If I replace the circuit with the component that I did, it does not work and there are no errors or warnings to see ive done something wrong.

  Ive my files attached

  There is the original circuit

  The circuit, that I used to create the EIF file.

  My cir file.

  and the new circuit with the added component

  Your help would be much appreciated, I am interested to know how it works

  Sorry wrong answer to and joining the new circuit with the addition of component, like I can join only three files

  Hi Cruizerdog,

  You can build a model SPICE of a circuit only when the components you used have a SPICE syntax, Multisim's database digital parts are not SPICES, it is based since XSPICE.  The model that you have tried to create won't work.

• component in Multisim

  Hi guys,.

  I just started to learn in Multisim.  I tried to add a 4011 and 4017 CMOS Gate in my circuit, but I do not know how to connect VDD and GND to the ICs.  Because there is only input and output pins.  I also wonder if I can expand the 4017 itself on my diagram.  I know how to increase the zoom of the entired schema.  Please advise, thank you.

• by using labview co-simulation, how to control the PWM market factor in multisim

  I am new to the use of Multisim with LabVIEW using co-simulation. I would like to ask if there is a PWM component in Multisim, which can have its cycle have to be controlled using LabVIEW? I have an algorithm in LabVIEW that returns the duty cycle values between 0 and 1, representing the percentage of duty cycle.

  How can I control the PWM market factor in Multisim using LabVIEW co-simulation?

  Thank you very much

• Could not find LM238 regulator of tension in Multisim

  I am new to Multisim.  I can't find a LM238 voltage regulator in the library under sources power supply voltage regulators.  In fact, I did a general search and could not find anywhere.  What is usually done in a case like this?  My intuition tells me that I wouldn't need to redraw my circuit just because I can't find a component in Multisim.

  Thanks in advance.

  Hello

  We don't have a model for the LM238, but we have a model for the LM138. According to this data sheet, the LM138, the LM238 and the LM338 are identical with the exception of the beaches of operating temperatures. You can place a component LM138 to the master database and use it for the simulationand implementation.

  Hope that helps.

  I haven't studied your ad but clearly the xU1 call isn't in a SPICE compatible format. The definition of subcircuit PA50 has 7 knots. Your call xU1 has 12! Nodes U1_OPEN_11 and U1_OPEN_12 exist anywhere else in the document.

• Conversion of IBIS to SPICE

  Hello

  I would like to convert spindle IBIS models to patterns of behavior SPICE I can import in multisim. I then combine these models of PIN with others built in components to make a simulation of end to end. I tried the free converter of Intusoft and get several errors when I import the SPICE circuit in a new component. My question to the group is, does anyone know of an IBIS in the converter of SPICE (free of preference, but ready to buy something if necessary) that generates a code that can be imported directly into a component of multisim with no editing? I guess that I would accept a small change, but I have several pins to bring and don't want to risk screwing the underlying model

  -Steve

  Hi Steve,.

  There is no particular way to IBIS spice that is recommended for work in Multisim. I think that if there is no chance of finding that the Spice model would be the best option. There are some other forums with more information on IBIS to spice. It seems that thay use the same tool that you have.

  Hello

  If you cannot find a component in Multisim, you can always create it using the Component Wizard (Tools menu), this is a basic tutorial:

  Creating components 101

  To create a component simulatable, it need a SPICE model. SPICE models are therefore created by manufacturers, visit the manufacturer's Web site to see if they have the model you need, you can also use a search engine.

  For your reference, I have attached a file Multisim with the LM723. You can save it in youruser database, just right-click on the component and select Save to DB component.

  I hope this helps, welcome to Multism!

  Kind regards

  Hello

  I'll expand a bit what Angela said on the. ENDS and then try to clear up the pins.

  The SPICE model that you use for the PA78 includes several subcircuits and models. Best practices for creating a component in Multisim are having one. SUBCKT or. MODEL for each component. The point of this is to ensure that the additional models or models contained so that they do not interfere with each other in the final netlist. The best way to solve this problem is to move the. ENDS during the main subcircuit until the end of the complete draft - so, instead of simply add the. ENDS at the end, you must also remove the first. END of line in the file. For this circuit, you probably don't need to do it, however in general, it's a good idea to do by making a component like this.

  With respect to the pins, step 6 of the component wizard asking you order the pins will be used in the model. The (original) model that you have only 10 knots, so it isn't a problem if you have only 10 pins there. If you have 12 pins on your symbol, and only 10 model nodes, then you score just two unused pins as "NC"(vous pouvez également ajouter deux broches"fausses"pour le.) ". SUBCKT which is what you did, but you have not).

  For the rest of the pins, see the. SUBCKT line and comments just ahead of him:

  * PINOUT ORDER +IN -IN IL OUT +VS -VS CR+ CC+ CR- CC-* PINOUT ORDER  7   6   1  2   12  4   8   11  10  3.SUBCKT PA78 7 6 1 2 12 4 8 11 10 3
  

  Comments indicating the order of broaching tell you the order in which the terminals must be indicated when you use the PA78. SUBCKT. As you can see on the. Line SUBCKT and comments, even if IT is pin 1 on the component, it should actually be listed third when you use the. SUBCKT. It's asking you to step 6 in the component wizard. Step 6 allows you to specify the order in which to use the pins to Multisim. The comment you indicates that + is the model node 1, - IN is model node 2, IT is the model node 3, etc., and then you say Multisim by setting the number of nodes of model

• Multi resistance vs ultiboard imprint imprint

  Hello

  I placed a chip-0603 resistance on mulstisim, and when I transferred the ultiboard design, he was placed as a RESC1608X63.

  After nodding with routing, I decided that I needed a wider space between the resistance and that an imprint of RESC1608X84 adapts well.

  After changing the footprint in ultiboard, I commented back to multisim - but there multisim can't find the RESC... X 84 imprint.

  How can I create a link between the different types of RESC1608X * to the footprint of chip-0603 CPI multisim?

  Thank you

  ADI Z.

  Hello

  The two programs have the same database, but there may be cases where a fingerprint in Ultiboard who is not assigned to any component in Multisim is not visible to Multisim. The opposite is as I said to save the component in a different database than the master.

  I hope this helps.

• Component USB 6008 in Multisim

  I conceive my system in Multisim 12 and I wanted to include OR components of the database.

  I need a component for the NI USB-6008 case and the other for the NOR cDAQ-9174 with two NI9217.

  My question is: these elements already exist (in the database, on the Web site of OR or a third party) or what I have to design?

  Thank you

  Here is an example of a database of these parts NOR (symbol only):

• Coaxial connector in Multisim component

  Hello

  Im looking for a component of coaxial connector in the Multisim database as well as the site of components listed here. But I couldn't find one. Can someone get me a clue on how to find it. Thank you.

  hers,

  There are several symbols of 2-pin connector that you could use and attach them to the available Ultiboard fingerprints or footprints BNC customized based on what it takes, however, here is a diagram with a BNC connector for example with a standard configuration of symbol of the BNC.

  Do not hesitate to register for databases, and customize with no specific information (that was created for a 50 ohm coax).
