|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''',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 '''error'''s. 

|-
|02:56
|Both errors say that the '''terminal'''s have no power sources.

|-
|03:00
|Click on the '''Close''' button.   

|-
|03:03
|In the '''schematic''', the '''error node'''s 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 flag'''s 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 '''node'''s 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 '''tab'''s 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 '''error'''s in circuit schematic

|-
|06:50
|To generate '''netlist''' for circuit.
