00:01 Dear Friends,
00:03 Welcome to the spoken tutorial on Electric rule check and Netlist generation in KiCad.
00:09 In this tutorial, we will learn-
00:12 * To assign values to components
00:14 * To perform electric rule check and
00:17 * To generate netlist for schematic created.
00:21 We are using Ubuntu 12.04 as the operating system
00:25 with KiCad version 2011 hyphen 05 hyphen 25 for this tutorial.
00:33 Basic knowledge of electronic circuit is pre-requisite for this tutorial.
00:38 User should also know how to design circuit schematic in KiCad.
00:42 For relevant tutorials, please visit the link: spoken hyphen tutorial.org
00:49 To start KiCad,
00:50 Go to the top left corner of ubuntu desktop screen.
00:56 Click on the first icon i.e. Dash home.
01:01 In the search tab, write "KiCad" and press Enter.
01:10 This will open the KiCad main window
01:13 Click on EEschema tab.
01:17 An Info dialog-box appears saying it cannot find schematic.
01:21 Click on OK.
01:23 We will use the file 'project1.sch' created earlier.
01:29 Go to File menu and click on Open.
01:33 Select 'project1.sch' from desired directory.
01:44 We will now assign values to components.
01:49 Let us assign value to 'R2' component.
01:54 Keep cursor over 'R', corresponding to 'R2' resistor.
02:01 Right-click and choose Field Value.
02:05 This will open Edit Value Field window.
02:11 Type "1M" and click on OK.
02:17 As you can see, '1M' (i.e. 1 mega ohm) value is assigned to the resistor 'R2'.
02:24 I have already assigned values to other components in the similar way.
02:29 Next step is to perform electric rules check on this circuit.
02:36 Go to top panel of 'EEschema' window.
02:39 Click on Perform electric rules check button.
02:44 This will open the EEschema Erc window.
02:48 Click on Test Erc button.
02:52 We can see that there are two errors.
02:56 Both errors say that the terminals have no power sources.
03:00 Click on the Close button.
03:03 In the schematic, the error nodes are pointed by arrows.
03:12 Let us connect a power Flag here. So, then KiCad will know that we are going to connect a power supply here.
03:22 For this,
03:24 On the right panel, click on Place a power port button.
03:29 Now, click on the 'EEschema' window to open the component selection window.
03:34 Click on List All button and you can see list of power notations.
03:40 Choose PWR_underscore FLAG and click on OK.
03:49 We will place the Power flag near 'VCC' terminal.
03:55 Click on the EEschema to place it.
03:59 We need two such power flags since there are two errors of such type.
04:05 Keep the cursor on the power flag and then press 'c' to copy it.
04:10 Place this power flag near the ground terminal.
04:15 Now, we will connect the power flag with wires. Go to right panel and click Place a wire button.
04:24 Now, connect the power flag to VCC terminal.
04:35 Similarly, connect the power flag to the ground terminal.
04:44 We will now run the Schematic ERC check once again to confirm.
04:49 For this, click on the Perform electric rules check on the top panel of 'EEschema' window.
04:55 This will open the 'EEschema Erc' window.
04:58 Click on Test Erc button.
05:01 We can see that there are no errors.
05:04 Click on Close.
05:07 Now, let us see how to generate Netlist.
05:10 Netlist gives information about list of components and nodes that connect them together.
05:16 We will see the use of netlist as we proceed further in this tutorial.
05:20 For generating netlist, go to the top panel. Click on netlist generation button.
05:27 This will open up the Netlist window.
05:31 This window contains tabs which allow you to generate netlist in different formats.
05:38 For KiCad we will use Pcbnew tab.
05:42 Keep Default format option checked and click on Netlist button.
05:48 Note that it saves the netlist file with name 'project1.net'.
05:54 Please note that when the netlist is generated, the file is saved with '.net' extension.
06:00 Click on the Save button.
06:02 Let me resize the window.
06:04 Click on the Save button.
06:06 Netlist file contains information about components, in the circuit, required for printed circuit board design.
06:14 We will see the use of this netlist file in another tutorial.
06:20 Go to File menu and choose Save Whole Schematic Project to save this schematic.
06:27 Go to File menu and choose Quit to close 'EEschema' window.
06:32 In KiCad main window,
06:34 Go to File menu and choose Quit. This will close the KiCad main window.
06:40 In this tutorial, we learnt-
06:44 * To assign values to components
06:46 * To check and correct for errors in circuit schematic
06:50 * To generate netlist for circuit.
06:53 Watch the video available at the following link.
06:56 It summarizes the Spoken Tutorial project.
06:58 If you do not have good bandwidth, you can download and watch it.
07:02 The Spoken Tutorial project team:
07:04 * Conducts workshops using spoken tutorials.
07:07 * Gives certificates for those who pass an online test.
