| 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

| 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.  

| Basic knowledge of electronic circuit is  pre-requisite for this tutorial.

|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.  

 

| 01:01

|In the search tab write KiCad and press Enter  

|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.  

| 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.  

|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.  

|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

| 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.  

|Click on the Save button.  

| 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

| 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

| 06:46

|To check and correct for errors in circuit schematic

| 06:50

| To generate netlist for circuit.
