Improving the Appearance of your designs in Multisim

As good engineers often put all our attention on the design and operation of a circuit, once it is ready and we need to report the results simply copy and paste the circuit regardless of its appearance, this is where we must ask: Does the capture of the circuit is organized? Is it easy to understand? Am I putting notes detailing their work?

educational and professional level is necessary to document a design for the best because this way is more understandable and easy to modify in the future. In this article I show the tools available in Multisim to improve the appearance of the designs.

's start with the graphical annotations, text, lines, shapes and images. In Multisim can find these options on the menu Place. To place text labels simply select that option, then click on the workspace and capture the desired text:

multisim

Once placed we can change the text size, font, etc.. Simply right click on the text and select Font ... in the context menu. Indeed, the text labels are floating, they can move freely.

Just below the text option in the menu on Multisim Place, is the graphics :

multisim

C on them we can add lines, shapes, and even import an image bmp:

multisim

As in the text, if we click right on a line or geometrical figure, we can change its color and pen style, fill type and to create arrows.

My favorites are the Comments , this option is also on the menu on Multisim Place. The comments are small text labels that are visible when approaching the mouse pointer:

multisim


We can also customize by right-clicking on them.

No circuit is complete without its Title Block which contains the title of the design, designer name, etc. Multisim has several templates you can use, for this go to the Insert menu >> Block T heading for ... and select a template. For example:

multisim

By default the Title Block are in English, but by right-clicking on them can be edited. Once we published double-click to enter information.

If you require printed circuit first thing you have to do is set the Print Options . These options will find the File menu Multisim. Here we find the Print Setup Circuit: sheet size, orientation, margins, etc.. There is also an option to select printing of the instruments.

The next time you design a circuit in Multisim, remember to use these options to document it better.

Until next time.

Creating a LM386 Audio Amplifier in Multisim

a few days ago followed this blog Multisim told me he was looking to simulate the component LM386 audio amplifiers. This component is not included in the Multisim database, but if we can create SPICE model using the Component Wizard . I did a search on the Web and to locate a SPICE model for the LM386, it is noteworthy that the model is not guaranteed, but early tests have been successful. So then I share a tutorial on how to create this custom component in Multisim. If you want to see a more basic tutorial on creating components visit the article Creating Components in Multisim Basic.

The LM386 is a power amplifier for use in low voltage amplifiers typically used in AM-FM radio. The spec sheet can be downloaded here . SPICE model for the LM386 I found this discussion forum . Only copy the model to notepad and saved it with a. Txt. The following figure shows an excerpt of this model:

multisim

With the LM386 spec sheet and we now SPICE model Multisim in English and select the menu Tools ú >> Components Wizard. In the first step we entered the overview of the component:

multisim

In step 2 we add the information ng footprint (footprint) for the component, this is necessary in case you later need to transfer the design to Ultiboard to create the PCB. For this, click on the button Select a trace. According to the spec sheet this component is available in several encapsulated in this case I selected the print M08A:

multisim


multisim

can now edit the symbol, you click on the Edit button to open the Symbol Editor in Multisim is very easy to use. I made a simple symbol:

multisim

Step 4. Assign terminal type (bidirectional, input, etc) to each pin:

multisim

We mapped the symbol terminals with the terminals of the mark:

multisim

Very important copy and paste the contents of the SPICE model for the LM386:

multisim

The next step is very critical and this is where most of the time they make mistakes. Here we map the nodes of the model with the terminal symbol. This information is usually at the beginning of the SPICE model. If we open the text file containing the model for the LM386 going to see that the configuration is one to one, for example, node 1 est mapped to the terminal to g1 (Gain 1), node 2 with the terminal inn (-Input), etc. There is not always the ideal case, so you should be cautious:

multisim

list, save the component in the User Database . We can even create a new Family :

multisim

To test I set up a typical application contained in the specification sheet. Is an amplifier with a gain of 20:

multisim

1mVp For an input of 500 Hz we have the following output:

multisim

I hope you have enjoyed this tutorial and find it helpful.

Once back in this intense weekend in Fuerteventura On balance:
; The four members of ORT Arista completed the test. Fernando de Armas and Fernando Gonzalez in the race, improved their personal bests. For his part, Sergio Jover Chencho Yanes and participated in "Road", enjoying a massive two-day test duration. The story put Sergio bike, with a serious fault in the first few miles, he was forced to make a mechanic for most of the first day and running with a borrowed bike on the second day. Here some pictures

Creating a Virtual Prototype

When we are designing a circuit in Multisim use the simulation to give us an idea of \u200b\u200bthe behavior of the circuit under certain scenarios. After we built a physical prototype to connect to real signals for best results. Very often we find from small to large differences between the results of the Multisim simulation and actual measurements.

These differences are due not only to the actual components have certain tolerances, but also the fact that our simulation with Multisim all input signals are ideal, ie not subject to noise fluctuations, fades, etc.

But what if instead of using the ideal sources feed our electronic design simulation with real data previously captured and stored? Definitely the Multisim circuit simulation results give us more attached to reality. Even no need to build physical prototypes in early design stage.

With Multisim this is possible thanks to the concept of Virtual Prototype . To create it we need first to capture the input signal and stored in a LVM file format. This format is proprietary LabVIEW and is based on ASCII. Once the data stored in LVM format, sent to call the file using a signal source in Multisim, the Voltage Source LabVIEW LVM, and then connect this source to our circuit.

Let's see this more in detail with an example.

Here's a circuit that serves captured in Multisim to filter the signal from the heartbeat. This circuit is the stage of a medical device.



multisim

To test the filter in Multisim could connect a function generator, select a sine wave, experiment with different amplitudes and frequencies, and finally analyze the results. However, those results distarían far from reality because the electrical signals from heartbeat are arbitrary. However, we can create a virtual prototype and test the circuit with a real signal.

The first step is to capture and store the signal of interest. For this we need a sensor or transducer and data acquisition hardware. Later we would use LabVIEW or LabVIEW SignalExpress to save the data acquired in an LVM format. This stage goes beyond the scope of this article, but if they would like to know more do not hesitate to tell me.

LVM The corresponding file is as follows:

multisim

Now in Multisim will place the source LVM _ VOLTAGE into Group SOURCES, Family SIGNAL_VOLTAGE_SOURCES :


multisim
In the properties of this source we can select the file you previously created LVM:

multisim

Ready, now simulate our circuit in Multisim and get a better answer:

multisim

The blue is the data signal to the input of our circuit, which were previously captured, is a real signal. Red is the filtered signal after passing through the circuit.

As you can see, the Virtual Prototype is a powerful tool that can help us improve our simulation results and test the circuit without need for costly physical prototypes. Of course, a key part of this method is to capture the signal as it requires specialized hardware and software. If you want to learn more about this part let me know to write an article regard.

Mozart's Andante Grazioso From Unleashed

We're going to FUDENA

Fuerteventura from North to South on a mountain bike is the challenge of ORT Arista on 30 and 31 October. The tour takes place along 150 km of distance separating Corralejo in the north of the island of Morro Jable in the south, by 90% through roads, tracks and paths. This allows us to enjoy the arid beauty of Fuerteventura, through volcanic badlands, jable areas (dunes), rocks, volcanoes, endless beaches ...
Chencho, Sergio Jover, Ferko and Fer be at the start of the MTB test, which brings together almost 1000 athletes this weekend in Fuerteventura.
