Programs for simulating electronic circuits in Russian. Qucs - open-source CAD software for modeling electronic circuits
EDA (Electronic Design Automation) is software for developing and testing electronic equipment. In the most general sense, Sprint Layout, which is so widespread in the Russian-speaking environment, can be classified as EDA. More well-known (and more complete products) include Eagle, DipTrace and Proteus. But they all have one small drawback - they are paid. Someone might object: the same Eagle, they say, also has a free version, albeit somewhat limited. However, these restrictions sometimes become not so much a hindrance as an irritation, such as the inability to position elements off the board, which makes it difficult to redistribute already located parts. Therefore, let's talk about KiCad - until recently little-known, but now gaining popularity software, somewhat burdened with cross-platform, but at the same time actively developing (the latest stable version was released in October 2014). In a couple of articles I will try to talk about the basic techniques and pitfalls of working with KiСad. As an example, let's take a simple Step-Up converter circuit on.
KiCad Program Overview
The main KiCad window is divided into several blocks
- The main menu where you can create or open a project, archive it in zip or unpack it, specify a text editor for viewing files (for example, a list of elements) and an application for viewing PDF, select a language (currently there are 19 languages in the list, including Russian), read the help and copy full information about the installed version to the clipboard.
- The second block contains (from left to right): creating a new project; creating a project from a template (there are no templates yet, but you can create them yourself; such templates will be added to the “Custom” list); opening an existing project; saving all files, be it a circuit diagram or a printed circuit board; archiving the current project in zip; updating the list of project files.
- The third block contains the actual list of files - everything that has a name that matches the name of the project is displayed here.
- The buttons of the fourth block allow you to navigate between the following editors: Eeschema - editor of electrical circuit diagrams of the device; CvPcb - comparison of component seats (in other words, selection of the body of a particular part); Pcbnew - printed circuit board editor; Gerbview - Gerber file viewer; Bitmap2Component - used to create logo images or to create components from existing images. Calculator - contains utilities such as a stabilizer calculator, tables of recommended track thicknesses for printed circuit boards, resistor color coding tables, etc.
- Finally, the last block displays the actions we performed with the current project (what was opened, what was saved, etc.).
The creation of any device begins with the creation of a new project. Therefore, click on the button “ Start a new project».
Select the folder for the future project, write its name, click “ Save", regardless of the style of my windows, in Windows they will be familiar and familiar.
The project name will appear in the left column and we can finally click on the button Eeschema. An editor like this will open...
And KiCad will happily inform us that a certain file is missing. Everything is fine, it just reminds us that we haven't saved the diagram yet, so a blank sheet has been created. In general, KiCad's twists and turns of logic are sometimes amazing. What’s even funnier is that this miracle is supported not by just anyone, but by CERN themselves.
But we digress, let's press OK. In the window that opens, we see the sheet on which our future diagram will be located. Actually, it can be located outside of this sheet, but these parts simply will not be printed. Around the workspace we see a bunch of different buttons; there is no point in explaining the purpose of each of them, because a hint pops up on each of them when you hover (naturally, in Russian). It is worth identifying only the main ones:
Don't be alarmed, everything is not as difficult as it seems at first. As a circuit, as mentioned above, I chose a converter based on MCP34063, also known as MC34063. The diagram is taken from the datasheet:
First of all, let’s look at the menu item “ Settings", where in addition to color settings, appearance parameters (grid pitch, connection thickness, etc.), we are interested in the item " Library" Libraries in KiCad, like in Eagle, contain components used in constructing a circuit. Let's make sure that the files supplied with KiCad are connected and present in the list.
Other libraries can be easily Googled and added via the " Add"(which is quite logical). I also advise you to download component libraries converted from Eagle. However, you should not include all the files at once - this can lead not only to slower loading of the project, but also to annoying messages about duplication of components in libraries. Having dealt with the little things, click on the button “ Place a component" in the right panel (or the item " Component" in the menu " Post") and click anywhere on the sheet.
In the window that appears, write in the “Name” field: 34063 - here, unlike Eagle, you do not need to know the exact name of the component, just a part of it is enough.
You can also select a component from the list (button " List of all") or by selecting a suitable symbol (" Select by browsing"). Click OK. If the entered designation appears in several components, we are prompted to select the one we need.
Place the symbol on the sheet.
Attention, rake! KiCad inherited the good tradition of hotkeys from Unix systems. To move a positioned component, it is not enough to simply click on it. You should move the cursor over the component and press the Latin [M] (from English Move) on the keyboard, or right-click on the component and select the corresponding item in the context menu. In the same way, turn with the [R] key and drag (that is, move without breaking away from the chains) with the [G] key. We add a component through the combination, and a conductor through it. The same thing can be done through the context menu. Hotkeys may seem awkward, but in fact most of them are intuitive to a user familiar with English words. In addition, by memorizing a couple of dozen combinations, you can significantly speed up your work. So don’t be lazy and read the certificate, fortunately it has been completely translated into Russian.
Following the microcircuit, we add the remaining components to the sheet. To add passive elements, just write their more or less generally accepted designations (R, C, CP, etc.) in the “Name” field. Once selected, components remain in the “History List” field for quick addition.
To complete adding components, press the key or select the item “ Set aside the tool" To connect the circuits we use " Place Explorer».
It turns out something like this:
If the connection of conductors seems inconvenient (or if the circuit is divided into separate blocks), then it makes sense to use labels. They link separate sections of a chain, just like names in Eagle. KiCad has several types of labels (local, global and hierarchical). Global and hierarchical are used when the blocks of the diagram are located on several sheets and they need to be linked together. The most primitive one is enough for us, so we choose “ Place chain name(local label)".
Click on the desired connection and write the name of the label. At the same time, we select the orientation of the mark - where its connecting point will be located.
Attention, rake! KiCad does not permanently tie the tag to the connection like Eagle does. Once created, a tag can be moved like any other component, but in order for it to be “picked up” by a net, its connecting point must align with a connection on the net or component.
Having placed the necessary marks, we get the following picture:
Now let's add ground and power circuits. They belong to the tool " Place power port»
We write in the search bar “ GND».
Or select the desired component using the button “ List of all»
Having placed the land, we do the same with Vin, selecting the appropriate component. It will have to be connected to a separate conductor. To do this, take the tool “ Place Explorer", click on the desired section of the circuit and pull the conductor to the side. In order to end it not at the connection point, but in an arbitrary place on the sheet, double-click the mouse.
We place the power supply for our circuit. At the output it is enough to simply place a label like “ Vout».
Now let's designate the components and indicate their values. This is done quite simply: you need to hover the cursor over the component and press the [ key V] to assign a denomination and the [ U] to indicate the serial number. However, numbers can also be assigned automatically. To do this, press the button “ Label the components on the diagram»
In the window that appears, configure the notation parameters (you can leave it as is). If parts of the components have already been assigned serial numbers, then you can either continue the current numbering or start it again by first clicking on the button Reset designations».
Having finished with the preparation, click “Design components” and agree with the proposal to give serial numbers to everything. Let's arrange the denominations. Hover the cursor and press [ V]. If several components are in focus, KiCad displays a small menu asking us to specify which component we want to edit.
Finally, check the correctness of the diagram by clicking the “ Perform check...»
In the window that appears, you can configure the verification parameters - the rules for connections between pins (what is considered an error, what is a warning) on the “Parameters” tab.
On the “ERC” tab, click “ ERC test"... and we see error messages.
In this case, green arrow markers will appear on the diagram next to the problem areas. Selecting a line from the list of errors in the ERC window will take us to the corresponding marker. So what is our problem? Here's the thing: it's not enough for KiCad to just put a power port on the circuit; it also needs to indicate that the power port added through the power port is just a power port, and not something else. The apotheosis of crutches, in my opinion, but completely solvable. You just need to pick up the tool again " Place power port» and select the component in the list of ports PWR_FLAG.
The following symbol will appear on the diagram:
PWR_FLAG is displayed only on the diagram and is needed solely to successfully verify its correctness. We connect it to the positive power supply and the GND circuit. We run the ERC test again - there are no more errors.
Attention, rake! When microcircuits with pins that are not connected anywhere are used, the ERC test will swear in their direction. To prevent this from happening, the “Not Connected” flag should be set on all unused pins.
As a result, we ended up with this diagram:
To print it, click on the button on the top panel " Printing the diagram", or select this item in the menu " File».
Attention, rake! Linux users may encounter a problem where a blank sheet is printed instead of a diagram. This happens due to wxWidgets not working correctly with printers.
- a) update wxWidgets to version 3.0;
- b) use the export of the diagram to an accessible graphic format or to a PDF file, and then print it.
It’s not entirely clear what motivated the KiCad developers, but the familiar export is located in the “ Draw».
Here we select the format, adjust the color mode and image quality (default line thickness), and choose whether we need to export the sheet frame along with the diagram. That's probably all you need to know to get started with EESchema. And next time we will talk about the intricacies and creation of new components for libraries. Author of the review - Vetinari.
