|Welcome to the '''spoken tutorial '''on “'''Mapping components''' with''' footprints'''”.

|-
|00:06
|In this tutorial, we will learn''' '''to :

Add '''connectors '''to a''' schematic.'''

Map''' components''' with '''footprints''' using '''CvPcb.'''

Generate '''netlist''' for '''PCB design.'''

|-
|00:20
|This tutorial is recorded using-

'''Ubuntu Linux OS version 16.04''' and

'''eSim '''version '''1.1.2'''

|-
|00:32
| To practice this tutorial, you should know:

The basic concepts of '''electronic circuits.'''

To create''' circuit schematic''' in '''eSim.'''

To '''simulate''' the '''netlist''' in '''eSim.'''

|-
|02:10
| Let us learn how to map '''footprints''' with '''components'''.

|-
|02:15
|I will switch back to '''eSim Schematic''' '''Editor'''.

|-
|02:19
| The '''schematic''' contains '''plots, labels '''and '''sources, '''which are essential for '''simulation'''.

|-
|02:27
|These '''components''' are not required for '''PCB designing.'''

|-
|02:31
|Let us delete the '''components''' that are not required for '''PCB designing'''.

|-
|02:36
|Right-click on '''sine source''' and select the '''Delete Component '''option.

|-
|02:43
|Right-click on '''plot_v1''' that is '''U1 component''' and select the '''Delete Component '''option.

|-
|03:45
|Click once to place the '''connector''' on the right side of the '''schematic'''.

|-
|03:50
| We also need a '''connector''' at the input to connect the external '''power supply.'''

|-
|03:56
|We have already selected '''Place component''' tool.

|-
|04:00
|Click anywhere on the '''eSim Schematic Editor '''window'''.'''

|-
|04:04
| Type '''Screw underscore Terminal''' in the '''filter '''box.

|-
|04:09
|Click on '''Screw underscore underscore 01x02 '''from the list.

|-
|04:18
|Click '''OK '''button at the bottom right corner of '''Component''' '''Selection''' window.

|-
|04:24

|-
|04:35
|Right-click on '''Screw underscore Terminal underscore 01x02 '''component.

|-
|04:42
|Select '''Orient Component '''from the drop-down menu and select '''Mirror II (two) '''option.

|-
|04:50
| Now, let us connect the '''connector'''s using wires.

|-
|04:54
|We have learnt to place wires earlier in this series.

|-
|04:59
|You can refer to the prerequisite tutorials, if required.

|-
|05:04
|Let us connect '''pin 1''' of '''Screw_Terminal underscore 01x02''' to the wire connecting '''D3''' and '''D4'''.

|-
| 05:16
|I have connected rest of the '''nodes''' to their respective '''connectors.'''

|-
|05:21
| All the '''components''' are connected.

|-
|05:24
|Let us '''annotate '''the '''schematic''' and perform '''ERC '''for the '''circuit schematic'''.

|-
|05:31
| Please refer to the prerequisite tutorials to learn how to perform '''Annotation '''and '''ERC.'''

|-
|05:38
|Let us now save the '''schematic'''.

|-
|05:41
|Press '''Ctrl '''and''' S''' keys together to save this '''schematic.'''

|-
|05:46
|We will now learn how to map the '''components''' with their''' footprints.'''

|-
|05:51
|'''Footprint''' is the '''layout''' of a '''component''' which is placed on the '''Printed Circuit Board'''.

|-
|05:57
|Click on the '''Run CvPcb to associate components and footprints '''button at the top of the''' eSim Schematic Editor'''.

|-
|06:06
|This opens '''Cvpcb window.'''

|-
|06:09
|If you’re using '''Cvpcb''' for the first time, you will get a confirmation box.

|-
|06:15
|Here, click on the '''OK '''button.

|-
|06:18
|If you get another dialog box titled '''Confirmation, '''click on '''No''' button.

|-
|06:25
| The '''Cvpcb''' window is divided into three '''panels.'''

|-
|06:30
|The left '''panel''' shows the '''Libraries''' of the '''footprints'''.

|-
| 06:35
|The middle '''panel''' is divided into 3 columns.

|-
|06:39
|The first column in the middle '''panel''' shows the serial number.

|-
|06:44
|The second column in the middle '''panel''' shows the reference '''ID''' of the '''components''' used in the '''schematic'''.

|-
|06:51
|The third column in the middle '''panel''' shows the values of the corresponding '''components''', if any.

|-
|06:58
|The right '''panel''' gives a list of '''footprints''' available in the '''libraries'''.

|-
|07:03
| The top menu of '''Cvpcb''' window has 3 options to filter the''' footprints'''.

|-
|07:09
|This will filter the '''footprints''' by '''keywords'''.

|-
|07:13
|This will filter the '''footprints''' by '''pin count'''.

|-
|07:17
|This will filter the '''footprints''' by the '''library'''.

|-
| 07:21
| Now we will map the '''components''' with their appropriate '''footprints'''.

|-
|07:26
| Click on the option '''Filter footprints list by library''' from the top menu.

|-
|07:33
|If any other filters other than '''Filter footprints list by library '''are selected, please uncheck them.

|-
| 07:41
| Please note that we are designing a '''board''' for '''Through Hole components'''.

|-
| 07:46
|'''Footprints''' which are meant for '''Through hole components''', will have '''THT '''in their description.

|-
| 07:53
| '''Footprints''' which are meant for '''Surface Mount Device components''', will have '''SMD '''in their description.

|-
|08:00
| Click on '''C1, '''the first row '''C1''' will be highlighted.

|-
|08:05
| Click on '''Capacitors_THT '''from the leftmost '''panel''' for selection of '''footprints''' of '''Through hole capacitors'''.

|-
|08:15
| The list of '''Capacitors underscore THT footprints''' for selected component '''C1''' will be available.

|-
|08:24
| We can also view the selected '''footprint'''.

|-
|08:26
| To do so, select any '''footprint '''from the right '''panel'''.

|-
|08:32
|Click on '''View selected footprint''' from the top '''panel'''.

|-
|08:37
| This will open '''footprint''' window which displays the image of the selected '''footprint'''.

|-
|08:43
| Now let us map the '''associated footprint''' for '''component C1.'''

|-
|08:48
| Let us locate the '''footprint''' with '''D 5.0 mm''' and '''P 2.50 mm'''.

|-
|08:55
| Double-click on it to '''assign''' this '''footprint'''.

|-
|08:59
| For '''J1 connector''': Click on '''J1, '''click on '''Connectors underscore Terminal underscore Blocks '''from the leftmost '''panel'''.

|-
|09:10
|Locate '''TerminalBlock underscore Altech underscore AK300 hyphen 2 underscore P5.00mm '''in the rightmost '''panel'''.

|-
|09:24
| Double-click on it to '''assign''' this '''footprint''' to '''J1'''.

|-
|09:28
| For '''J2 connector''': Click on '''J2''', click on '''Pin_Headers '''from the leftmost '''panel'''.

|-
|09:36
|Locate '''Pin underscore Headers colon Pin underscore Header underscore Straight underscore 1x02 underscore Pitch2.54mm '''.
Double-click on it.

|Locate '''T0 hyphen 220 hyphen 3 underscore Vertical '''from the rightmost '''panel'''.

|-
|10:20
| Double-click on it to '''assign''' this '''footprint'''.

|-
|10:24
| I have mapped rest of the '''components''' with their appropriate '''footprints'''.

|-
|10:29
| Now we will save this '''footprint association'''.

|-
|10:33
| Click on '''Save footprint association in schematic component footprint fields''' at the left corner of the top toolbar.

|-
| 10:41
|This is a very important step and should not be skipped.

|-
|10:45
| It '''assigns''' the selected '''footprints''' to the '''components''' present in the '''schematic'''.

|-
|10:50
| Let us now generate the''' netlist '''for '''circuit schematic '''required for''' PCB layout'''.

|-
|10:56
| I will go back to the '''eSim Schematic editor''' window.

|-
|11:00
|Click on '''Generate netlist '''button at the top of '''eSim Schematic Editor '''window.

|-
|11:06
|Click on '''Pcbnew''' tab Check the option '''Default format.'''

|-
|11:20
| '''dot net netlist''' file contains information about '''components''' and '''footprints assigned'''.

|-
|11:26
| This is crucial for '''Printed Circuit Board designing'''.

|-
|11:30
| With this, we come to the end of this tutorial. Let us summarize.

|-
|11:36
|In this tutorial, we learnt to :

Add '''connectors '''to a '''schematic.'''
