|-
|00:01
|Welcome to the '''spoken tutorial '''on “'''Setting Parameters for Designing PCB'''”.

|-
|00:07
|In this tutorial, we will learn to -

Read a''' PCB netlist.'''

Draw '''outline '''and setup '''design parameters''' for a '''board.'''

Move and orient '''footprints'''.

|-
|00:22
| This tutorial is recorded using -

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

'''eSim '''version 1.1.2

|-
|00:34
|To practice this tutorial, you should know:

To design and '''simulate''' a '''circuit''' in '''eSim.'''

To map '''components''' with '''footprints''' in '''CvPcb.'''

To create '''netlist''' for '''PCB Design''' in '''eSim.'''

|-
|00:50
|If not, watch the prerequisite '''eSim''' tutorials on this website.

|-
|00:56
| I have opened''' eSim''' on my machine.

|-
|00:59
| Let us open '''7805VoltageRegulator '''example.

|-
|01:14
| Click on '''Open Project '''button from the left toolbar.

|-
|01:21
|Click on '''Desktop'''. Click on '''7805VoltageRegulator.''' Click on '''Open '''button at the bottom right corner.

|-
|01:30
| Click on '''Open Schematic''' button from left toolbar, to open the '''schematic'''.

|-
|01:37
| The '''schematic''' will open. Click on '''Cvpcb '''shortcut at the top toolbar.

|-
|01:45
|I have mapped the '''components''' with appropriate '''footprints '''and generated '''netlist '''for it.

|-
|01:51
|I will switch back to the '''eSim schematic editor'''.

|-
|01:54
|Click on '''Tools''' at the top toolbar and select the '''Layout Printed Circuit Board''' option.

|-
|02:02
|If you get a '''Confirmation''' box, click on '''Yes'''.

|-
|02:07
| An empty '''layout screen''' is seen in the '''Pcbnew '''window.

|-
|02:11
| On the top toolbar, click on '''Read netlist.''' '''Netlist''' window will appear.

|-
|02:19
| Click on '''Browse '''button, and navigate to '''Desktop '''location.

|-
|02:25
|Double-click on '''7805VoltageRegulator.'''Click on '''7805VoltageRegulator.net'''.

|-
|02:35
|Click on '''Open '''button at the bottom right corner of this window.

|-
|02:40
| The '''netlist''' will be loaded.

|-
|02:43
| Click on '''Read Current Netlist '''button at the top right corner of '''Netlist '''window.

|-
|02:49
|If there is an error it will appear in red color in the '''Messages''' window. In my case, there are no errors.

|-
|02:56
|Click on the '''Close '''button at the top right corner of the '''Netlist '''window.

|-
|03:03
|The''' footprints''' mapped with the '''components''' appear on '''layout screen''' in a bundled manner.

|-
|03:09
| Let us draw an '''outline''' for the '''board''' we are creating.

|-
|03:13
| To place an '''outline''' for the '''board''' on '''Edge.Cuts''' '''layer,''' right-click on the '''layout screen.'''

|-
|03:19
|Click on '''Select working layer.''' Click on '''Edge.Cuts.'''

|-
|03:25
| Alternately, working '''layer''' can be selected from the right side of the '''panel'''.

|-
|03:30
|Under the '''Layer '''option, working '''layer'''s of a '''board''' are listed.

|-
|03:35
|'''Front Copper '''and''' Bottom Copper''' will be used for placing '''tracks'''.

|-
|03:41
|'''Front Silk, Edge.Cuts '''and''' Margin layer'''will be used for placing text and dimension.

|-
|03:49
|Click on the right side of '''Edge.Cuts layer. ''' A '''blue arrow '''will appear next to the '''Edge.Cuts.'''

|-
|03:59
|Click on '''Place '''at the top toolbar of '''Pcbnew '''window.

|-
|04:04
|Click on '''Line or Polygon '''from the menu.

|-
|04:08
|A pencil tied to your cursor will appear on the layout screen.

|-
|04:13
|We will use this to draw the '''outline'''.

|-
|04:16
|Click on the '''layout screen '''and move the pencil horizontally to a certain extent.

|-
|04:22
|Click on the location where we want to finish the line.

|-
|04:26
|A yellow line will appear on the '''layout screen'''.

|-
|04:30
|We will draw a rectangular shaped '''outline''' using the method demonstrated.

|-
|04:37
| We have created a rectangular shape as the '''outline''' for the '''board'''. Press '''Esc''' key to exit '''Line or Polygon''' tool.

|-
|04:46
| Now let us separate and place the '''footprints'''.

|-
|04:50
|I will now zoom in to see the '''footprints''' on the '''layout''' clearly, using the '''F1''' key.

|-
|04:57
|Right-click on '''Screw underscore Terminal underscore 01x02'''.

|-
|05:04
|Select '''Footprint J1 on F.Cu''' and select the '''Move '''option.

|-
|05:11
|Move the cursor tied to the '''footprint''' horizontally towards left.

|-
|05:17
|Click once on the '''layout screen '''to place the''' footprint.'''

|-
|05:21
| To properly orient this '''footprint''', right-click on '''Screw underscore Terminal underscore 01x02.'''

|-
|05:30
|Select '''Footprint J1 on F.Cu.'''

Let us select the '''Rotate + '''option.

|-
|05:40
| Similarly we will move and orient all other '''footprints''', according to our design.

|-
|05:46
|All the '''components''' should be inside the rectangular '''outline''' drawn.

|-
|05:51
| Press '''Shift''' and '''?''' keys together.

|-
|05:56
|This will open all the keyboard shortcuts available under '''Hotkeys List '''window.

|-
|06:03
| We can use '''Hotkeys''' or the demonstrated methods for placing and orienting the '''footprints'''.

|-
|06:10
| Click on '''Close '''button at bottom right corner of the '''Hotkeys List '''window.

|-
|06:15
|You may or may not see white wires, representing interconnected '''footprints'''.

|-
|06:21
| If you do not see them, click on '''Show or Hide board ratsnest''' button at the '''panel''' of '''Pcbnew '''window.

|-
|06:30
|White wires are called as '''airwires'''.

|-
|06:34
| I have already moved and oriented the '''footprints''' to get minimum intersection between '''airwires'''.

|-
|06:40
| Let us set the '''parameters''' to place '''tracks''' on the '''layout'''.

|-
|06:44
| Click on '''Design Rules '''option given at the top side of the toolbar. Click on '''Design Rules '''from the menu.

|-
|06:53
| We will change the default '''track''' width from 0.25 mm to 1.2 mm.

|-
|07:00
|Click on the window below '''Track Width.''' Let us clear the present value using '''Backspace '''key.
Type the number '''1.2.'''

|-
|07:10
| This will make all '''tracks''' placed in future, of '''1.2 millimeter''' width.

|-
|07:16
|You can select the '''track''' width according to your requirements.

|-
|07:20
| Click on '''Global Design Rules''' at the top of the '''Design Rules Editor''' window.

|-
|07:27
|Click on the tab in front of '''Min track width.'''

|-
|07:32
|Let us clear the present value using '''Backspace''' key. Then type the number '''1.2 '''in this space.

|-
|07:42
| This ensures that any '''track''' placed on any '''layer,''' is of minimum 1.2 mm width.

|-
|07:50
| Click on the '''Ok '''button at the bottom right corner.

|-
|07:54
| Now let us check the '''drill hole''' size of '''X1''', that is '''Lm_7805'''.

|-
|08:02
| Place cursor on '''Node 1''' of '''X1''' and press '''E''' key.

|-
|08:08
| '''Pad Properties '''window''':'''

|-
|08:11
| We can see the '''drill hole '''properties such as shape, size of this particular '''pad'''.

|-
|08:17
|We can see the default '''drill hole''' size for this particular '''pad''' is 1 millimeter.

|-
|08:23
| The default '''drill hole''' size and shape for different '''footprints''' may vary. We can change it according to our need.

|-
|08:32
| Click on the '''Ok '''button at the bottom right corner of the '''Pad Properties''' window.

|-
|08:38
| Let us press '''Ctrl '''and '''S '''keys''' '''together to save the work.

|-
|08:44
| With this, we come to the end of this tutorial. Let us summarize.

|-
|08:49
|In this tutorial, we learnt to :

Read a''' PCB netlist.'''

Draw '''outline '''and setup '''design parameters''' for a '''board.'''

Move and orient '''footprints'''.
