| Welcome to the spoken tutorial on “'''Laying Tracks on Printed Circuit Board'''”.

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

Place '''tracks''' on '''printed circuit board.'''

Add '''dimension''' and '''text''' on '''Silkscreens.'''

Generate '''Gerber files '''and view them.

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

'''Ubuntu Linux''' OS version 16.04

'''eSim '''version 1.1.2

|-
|00:31
|To practice this tutorial, you should know to:

Read a '''PCB netlist.'''

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

Move and orient '''footprints'''.

|-
|00:43
|If not, see the prerequisite '''eSim''' tutorials on this website.

|-
|00:48
| I have already opened '''eSim''' on my machine.

|-
|00:50
| Let us open example '''7805VoltageRegulator.''' I have saved this on my '''Desktop'''.

|-
| 00:59
| I have already read the '''netlist''', created an '''outline''' and set the '''design parameters'''.

|-
|01:05
|Click on '''Open Project '''from the left toolbar.

|-
|01:09
|And navigate to the location where you have saved this.

|03:39
| Let us move this cursor vertically, towards the bottom-right vertex of the '''board'''.

|-
|03:45
| Click once slightly below bottom-right vertex.

|-
|03:49
| Similarly, we will draw a rectangular '''ground plane outline '''around '''board outline.'''

|-
|03:56
| Please do not confuse '''board outline '''with '''ground plane outline.'''

|-
|04:01
|I have completed the '''ground plane outline.'''

|-
|04:04
| Note that the '''ground plane outline''' should lie outside the '''board outline'''.

|-
|04:09
|Right-click inside the '''board outline'''.

|-
|04:12
| Click on '''Fill or Refill all zones '''button from the menu.

|-
|04:17
| We have added a '''ground plane''' to the '''board'''.

|-
|04:20
| Press '''Esc''' key to exit the '''Add filled zones '''tool.

|-
|04:25
|Let us now perform '''Design Rule Check''' i.e '''DRC''', for the '''layout''' we created.

|-
|04:32
| It checks whether the '''design''' created is compliant with the '''Design Rules''' set earlier.

|-
|04:38
| Click on '''Perform Design Rules check '''present at the top of the '''Pcbnew''' toolbar.

|-
|04:44
