DS90LV032A spice model file

Hi, I can not find spice model file of DS90LV032A 3V LVDS Quad CMOS differential lne receiver and ADG3304 Low Voltage 1.2 V to 5.5 V,
Bidirectional, Logic Level Translators.
Is anyone can help me to link a spice model file of them, thanks a lot.

There are some free and commecial utilities that can generate one from the other, at differing levels of IBIS support (version #s, keywords, etc). I haven't done much of that and it's been a long time, so I can't help much with the specifics of it.
A web search of something like "IBIS to SPICE Conversion" yeilds some interesting resources.

Like I told another user I am no expert on model files. I have tried this file and Multisim will not recongnize it. I would recommend the following procedure if you can do it. Go into the component wizard and create a default Mosfet Using the Model Makers.. This will give you the correct syntax for the model file that Multsim can understand. If you know what the parameters mean from Pspice file then you can edit the model after it is created for you in Multisim and plug the numbers into it from the Pspice file. This should create a model that would work in Multisim. This procedure is theoretical on my part and you would have to try it to see if it works for you. It is possible that you don't have the Model Makers depending on your version of Multisim. If that is the case then we will have to try another approach.
I do not know the meaning of the Pspice parameters (i.e what does the L=XXXXX and N=XXXXX actual stand for). If you are unable to do this then maybe the NI Team can decipher this for you and post a model file that would work for you.
I am going to have to study the various parameter on these files to find out their meaning so I can be of better assistance when it comes to these model files. Right now I just don't have the time since I recently acquired a job that takes up a fair chunk of my days. I will contin ue looking into this as times permits for me.

Applicable Updates and Importing Spice Models

Two part question:
Just installed version 10.0.144 (as seen in help-about Multisim) from CD and since my company uses a proxy server, I will need to manually check for updates. How do I know which updates are available for this version ?
Next, and more importantly, I need to import externally developed Spice models, assign them a shape and be able to use them in a simulation. While you do have a method for importing a spice netlist, I do not see anything that applies to subckt models (files that contain a .subckt definition.

Hi there,
It is possible to configure the Multisim 10 updater to use a proxy server.
Launch the Support and Update Utility (SUU)
SUU will check for updates, but will fail if you haven't configured SUU to use the proxy server
On the main SUU window, click Settings
On the second tab labeled Internet Connection Settings, enter the settings for you proxy server
Click OK and restart SUU
The latest update of Multisim 10.0 will update your version to 10.0.343.
As for your second question, it is relatively easy to create symbols and components that use SPICE models. What you need to do is outlined in this tutorial: http://zone.ni.com/devzone/cda/tut/p/id/3173.
Hope that answered your questions.

How to export spice model from master db

I can't find a menu option nor DB manager option to select a component and export the spice model. Msim 10.1 full academic version with paid update service.

Hi there,
There are a few different ways to extract a component's SPICE model:
Transfer > Export Netlist: This will export the netlist for your design. So to export the SPICE model for one component only, simply place it down alone and then export the netlist.
Component Properties > Model tab: This method involves copying/pasting from the Model tab of the Component Properties dialog
Open the Database Manager
Edit the component
Select the Model tab
Copy/paste the SPICE model into a text file
Save with .cir extension
SPICE Netlist Viewer: In Multisim 11, there is also the ability to save a netlist from the SPICE Netlist Viewer, which displays the netlist live within a pane of Multisim

RS-485 transceiver spice model

Multisim Experts,
I have been on the hunt for an RS-485 transceiver spice model. In particular the MAX489, or any comparable full duplex transceiver. After many hours sorting through web searches I have come up empty handed. I was able to locate IBIS models for the transceiver, but converting IBIS to Spice using Intusoft's conversion program has been unsuccessful. I was wondering if anyone knew a good resource on how to write Spice models from existing IBIS parameters or data sheets? Or if perhaps anyone knew where to locate RS-485 models on the web?
Thanks for your time.

Multisim uses both SPICE and XPSICE simulation engine and there should be plenty of resources available on the Internet relating for these topics. Here are links where you can find the manuals:
SPICE:
http://esaki.ee.boun.edu.tr/~talays/spice/spice.pdf
XSPICE:
http://users.ece.gatech.edu/~mrichard/Xspice/Xspice_Users_Manual.pdf
The models you sent me will not work as is, there are minor syntax issues that needs to be modified and for it to work and here is a list:
1. No 'Param' statements were declared but a couple of statements uses a variable as a value, they did defined variable and was commented out, I guess they expect you to manually change it. The variables I am referring to are RTR and RTF:
Look for these statements:
*DEFINE {RTR}= 53.731k ;2.68V/1.44ns
B3 300 850 I= V(830) > 1.2   ? 0 : V(300,850) / {RTR}
Just replace RTR with the value like this:
B3 300 850 I= V(830) > 1.2   ? 0 : V(300,850) / 53.731
2.                  There are many instances where xy_array were used and unfortunately, Multisim does not support this syntax and you need to split the table into x_array and y_array separately.
For example the original model looks like this:
xy_array = [
+   -6.000 ,   -2.360
+   -5.000 ,   -2.360
+   -4.000 ,   -1.800
You need to change it to this:
+ x_array [-6.000 -5.000 -4.000 …..]
+ y_array = [ -2.630 -2.360 -1.800 ….]
3.                  You need to remove the some commas in the model
Original model:
+ fraction = FALSE, input_domain = 0.0,
Change to:
+ fraction = FALSE input_domain = 0.0
4.                  There are several duplicate subckt names declared and you should make them unique. I simply added an extra number at the end.
The attached file contain the modified model and test circuit, I am not sure what this component is suppose to but I connected some power sources to it and was able to simulate without an error.
I hope this help.

Data Modeler bug? - it keeps reporting missing physical model files

Hi,
I'm having a rather serious problem with the latest data modeler, Oracle SQL Developer Data Modeler 3.1.4.710. It keeps losing physical model files for some reason.
I started to notice that it was not generating all the tables in my small design. After hours of struggle I found multiple error messages in the log file:
2012-12-18 10:51:20,126 [Thread-71] ERROR XMLTransformationManager - Unable to load object from XML: C:\cygwin\home\Brian\codebase\models\data\Design\rel\395D160B-C7224B8EAD05\phys\D9582E4E-2ED963CB9D32\View\seg_0\A555DB9B-8864-9C0B-DCA8-BAC5231F55C6.xml

These messages appeared every time I opened my physical model (Oracle 10g).
After deleting and recreating the physical model the problem went away for a while. But after closing and reopening the design I started to see the errors again.
Has anyone seen something similar?
Regards,
Brian

Thanks Philip!
The workaround does the trick for the tables, primary keys and unique keys.
I have just observed that table level constraints show a slightly different behaviour.
Names show up like TCC5, TCC6, etc.
Seems the same problem as previously in SQL*Modeler forgets check constraint names
Is there a workaround for that problem too ?
I already noticed that there is no parameter NameChanged for a table constraint.

CATIA v4 3D & 2D .model files

Hi,
I have a CATIA v4 .model file that I open with Acrobat Pro Extended.
This model has 3D and 2D views in it. These appear in CATIA as separate "pages" or really views. When I open the .model in Acrobat Pro Extended I get a single page 3D document of the 3D model but the 2D drawings that were part of the .model are not included.
I also have a CATIA v4 .model that has only a single 2D diagram.
When I open this it shows the model tree but the display/page is blank.
Can Acrobat Pro Extended read/open all the data in a CATIA v4 .model file (2D & 3D)?
Thanks,
Jesse Perry

hi Jesse,
Unfortunately, Acrobat 9 Pro Extended cannot read 2D from Catia v4 model files. It only supports reading 3D from Catia v4.

Multisim: LT1568 Spice modell, AC simulations

Hi,
I'm building an input stage to an ADC, and need to do some signal conditioning before sampling. I'm thinking of using LT1568 for Low-Pass filtering, but when doing simulations in Multisim 13.0 I'm not getting the results I'm expecting.
I've provided my schematic, which is configured as a 4-pole LP filter with cut-off frequency at 5 MHz. When simulating it act's as a HP filter for some reason..
I've tried LTSpice and everything works fine, and I've contacted LT (Linear Technology) to get help but they suggest me to stick with LTSpice, which is not ideal for me.
I tried to make my own spice-model from code/description I found on the internet but with no success. Perhaps due to limited knowledge of spice.
Attached is the schematic
Thanks in advance
Sebastian

Hi,
The model you selected was made by Motorola and unfortunately, when this model was imported into Multisim, the comments to show what this model was designed for was removed. Some models will not work with single rail. I was able to find the library where this model came from and base on the comments, this op-amp model was designed for the following:
- Positive and Negative Slew Rate
- Quiescent Power Dissipation
- Maximum Positive and Negative
- Output Voltage Swing
- Input Bias Current
- Open Loop Voltage Gain
- Unity Gain Frequency
- Common Mode Rejection Ratio
(CMRR)
- Output Impedence (ac and dc)
- Output Short Circuit Current Limit
You can find the original model from here:

I need the ISO124 SPICE Model, or the component on Multisim. Can anyone help me?

People, I need the ISO124 model. Does anybody know how I can find it??
Thank you soo much!

Hi,
The SPICE model for the ISO124 is not available by the manufacturer. You can try contacting them and make a request for the model, sometimes they provide it upon a customer request.

Creating Diagram and model file programmatically

Hi,
Am trying to create the Diagram and model file programmatically.
I used the code similar to what is there in XXDiagramEditorUtil.createDiagram().
In the normal case (when i have an empty domain ie nothing is set into the domain object), the diagram and the domain file gets created and works fine.
Assume my model is of type XX, and that has a list of YY.
i create YY and set it inside XX.
Now when i create the domain file, the <YY> is set correctly inside <XX>.
But in the diagram file, i dont see the <children/> tags corresponding to the YY.
How would the appropriate <children/> tags be generated ?
i tried diagram.createChild(yy.eClass()), but the diagram file does not get generated.
Pls help.
AbstractTransactionalCommand command = new AbstractTransactionalCommand(editingDomain,
Messages.XXXDiagramEditorUtil_CreateDiagramCommandLabel,
Collections.EMPTY_LIST) {
protected CommandResult doExecuteWithResult(IProgressMonitor monitor, IAdaptable info) throws ExecutionException {
XXX model = createInitialModel();
YYY yyy = XXXFactory.eINSTANCE.createYYY();
yyy.setAttribute1("2");
yyy.setAttribute2("name");
model.getYYYs().add(yyy);
attachModelToResource(model, modelResource);
Diagram diagram = ViewService.createDiagram(model, XXXEditPart.MODEL_ID,XXXEditorPlugin.DIAGRAM_PREFERENCES_HINT);
if (diagram != null) {
diagramResource.getContents().add(diagram);
diagram.setName(diagramName);
diagram.setElement(model);
//diagram.createChild(yyy.eClass());
//diagram.insertChild(arg0);
try {
modelResource.save(.getSaveOptions());
diagramResource.save(getSaveOptions());
} catch (IOException e) {
return CommandResult.newOKCommandResult();

Hi ganesh,
you have two options to get it working.
The first one is using a CanonicalEditPolicy, which creates all Nodes and Edges for you based on your semantic model. This is easy to implement, but it has some drawbacks. Your editor will get dirty after opening it, because your Notation Model is changes and no layout information is available.
The better way is to create Nodes and Edges for each semantic element you created.
For your code snippet it might look like this:
XXX model = createInitialModel();
YYY yyy = XXXFactory.eINSTANCE.createYYY();
yyy.setAttribute1("2");
yyy.setAttribute2("name");
model.getYYYs().add(yyy);
attachModelToResource(model, modelResource);
Diagram diagram = ViewService.createDiagram(model, XXXEditPart.MODEL_ID,XXXEditorPlugin.DIAGRAM_PREFERENCES_HINT);
Node yyyView = ViewService.createNode(diagram, yyy, SemanticHints.YYY,
,XXXEditorPlugin.DIAGRAM_PREFERENCES_HINT);
//Set some layout information assuming you use a XYLayout
Bounds bounds = NotationFactory.eINSTANCE.createBounds();
bounds.setX(70);
bounds.setY(20);
yyyView.setLayoutConstraint(bounds);
Regards,
Andreas

I need the SPICE Model for DS1809 or the component in Multisim. Help mee!

Hey people, I need the SPICE Model for DS1809 (Digital Potentiometer) for Multisim. Does anybody have this?? Or any idea where to get. I searched for, but I coudn't find.
Thank you

Hi,
As you can see in this link the part is longer manufactured and it does not have a replacement.
In terms of functionality, you can try using the component PLL_VIRTUAL in Multisim to replace it in a high level simulation or create a new component of a replacement that you have the SPICE model of.
Let me know if you need any help.

RTD Platinum sensor Spice model

Does anybody have a spice model or can show me how to make one for a 20 ohm platinum ptc sensor with self heating ? I need to simulate it in a closed loop bridge circuit, I am an old fart that normally just uses paper and changes parts but this circuit is all smd.
Thanks doug W

Doug,
I created a simple RTD model that you can try. Use the TEMP pin to supply the external environment temperature as a voltage signal.
Take a look at the SPICE model and you should be able to figure out what's going on. Basically, its just a variable resistor modeled as I=V/R(temp), where temp is the adjusted temperature, a function of the external temperature and the power across the device.
Hope that helps!

View 3D model files as plain text in Visual Studio 2013

Hi, as the title says I'd like to be able to view 3D models as plain text in VS2013 and not through the built in model viewer that came in VS2012?
I havn't found a way to view .obj or .fbx files as plaintext in visual studio 2013 so I've had to temporarily change file extension or use a different editor.
So is there some way to disable the model viewer temporarily or toggle between text/model viewer?

Hello,
Welcome to MSDN forum. But I am afraid that the issue is out of support range of VS General Question forum which mainly discusses
the usage of Visual Studio IDE such as WPF & SL designer, Visual Studio Guidance Automation Toolkit, Developer Documentation and Help System
and Visual Studio Editor.
It seems that 3D model is related to games app such as DirectX app development. IN this case, we don’t have environment to research your issue. I suggest consulting your issue on DirectX and XNA forum for better support:
