| 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'''.

I will zoom into the '''layout screen.'''

|-
|02:24
| Click on '''node 1 '''of '''C2.'''

|-
|02:28
| Let us drag this '''track''' from '''node 1''' of '''C2''' to '''node 1 '''of '''J2, '''by dragging the cursor till '''node 1 '''of '''J2.'''

|-
|02:36
| Double-click on '''node 1 '''of '''J2 '''to complete the '''track'''.

|-
|02:40
| Similarly connect all the other '''nodes''' except the '''Ground nodes'''.

|-
|02:45
| Press '''Esc '''key to exit the '''Place Track''' tool.

|-
|02:49

|-
|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
