Time Narration
00:01 Dear Friends,
00:02 Welcome to the spoken tutorial on Mapping components with footprints in KiCad
00:07 In this spoken tutorial, we will learn
00:10 To map components with corresponding footprints.
00:13 Basic knowledge of electronic circuit is pre-requisite for this tutorial.
00:18 User should know how to design circuit schematic in KiCad,
00:23 And do electric rule check and netlist generation.
00:26 For relevant tutorials, please visit spoken hyphen tutorial.org
00:33 We are using Ubuntu 12.04 as an operating system
00:37 With KiCad 2011 hyphen 05 hyphen 25 for this tutorial.
00:47 To start KiCad,
00:49 Go to the top left corner of Ubuntu desktop screen.
00:52 Click on the first icon (i.e.)the Dash home.
00:56 In the search bar type 'KiCad' and press Enter.
01:04 This will open KiCad main window.
01:07 To open EEschema, go to the top panel. Click on EEschema tab.
01:17 An info dialog box will appear which says that it cannot find the schematic.


01:21 Click on OK.
01:24 I will use the circuit schematic of Astable multivibrator which was created earlier.
01:30 To do this, I will go to the File menu, click on Open.
01:37 I will bring this window in the visible area.
01:44 Choose the folder in which the file is saved.
01:50 and click on Open.
01:55 This will open the circuit schematic.
01:57 I will zoom in using the scroll button of the mouse
02:02 We have already generated the netlist for this circuit.
02:07 Let us now look at the process of mapping the components used in the schematic with footprints.
02:14 Footprint is the actual layout of the component which is placed in the Printed Circuit Board.
02:21 To start mapping of the components,
02:24 Go to the top panel of EEschema window.
02:28 Click on the Run Cvpcb button.
02:33 This will open the Cvpcb window.
02:37 It will also open a dialog box titled Component Library Error.
02:42 Click on OK button to close it.
02:47 Notice that it opens project1.net file. Please recall that we had generated this file in the netlist generation tutorial.
02:58 The Cvpcb window is divided into two panels.
03:03 The first column in the left panel is the serial number.
03:07 The second column shows reference id for list of components used in schematic.
03:14 The third column shows values of the corresponding components.
03:19 The right panel gives a list of footprints available.
03:25 Now we will map the components with their associated footprints.
03:30 We can see list of footprints available for selected component (i.e) C1 in the right part of Cvpcb window.
03:41 We will now view footprint corresponding to the selected component.
03:45 On the top panel of Cvpcb window click on View selected footprint
03:53 This will open footprint window which displays the image of footprint selected.
04:02 We can also see images of different footprints by clicking on them
04:12 I will close footprint window now.
04:15 For the first component C1, we will choose the footprint C1 from right panel.
04:22 To assign C1 footprint to first component, double click on the footprint.
04:27 As you can see, C1 footprint gets assigned to the first component in the list.
04:34 Similarly for second component C2 also we will choose footprint C1 by double clicking on it.
04:43 For the next component D1 we choose LED hyphen 3MM.
04:50 For connector P1 we choose SIL hyphen 2 from the right panel.
05:02 I will scroll down in the right panel to select it.
05:09 For R1 we choose R3.
05:13 For R2 we choose R3.
05:17 For R3 we choose R3.
05:22 For U1 i.e. LM555 we choose DIP hyphen 8 underscore 300 underscore ELL which is a standard eight pin IC footprint.
05:38 Now we will save the netlist by clicking on Save netlist and footprint files button on the top panel of Cvpcb window.


05:48 This will open Save Net and Component List window
05:54 I will resize this window for better view.


06:00 Click on Save to save this file. This will save the file and also close the Cvpcb window automatically.
06:13 Now the netlist is updated with footprints information.
06:18 Here the process of mapping the components is complete.
06:21 Go to the EEschema window. Now close this window.
06:29 Also close the KiCad main window.
06:35 This brings us to the end of this tutorial.
06:38 In this tutorial we learnt,
06:40 To map the components with corresponding footprints using Cvpcb window
