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_(underscroll)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.
