Time	Narration
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.
00:17	And 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 rule check on this circuit
02:36	Go to top panel of EEschema window.
02:39	Click on Perform Electric Rule 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 connects 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.
