Opening Slide
|| Welcome to the spoken tutorial on '''Uploading a Spice Device Model''' in '''eSim'''.
|-

|| '''Show Slide:'''
Learning Objectives

|| In this tutorial, using '''eSim''' we will learn -
* To create a '''Schottky Diode''' using the '''Upload''' option.
|-

|| '''Show Slide:'''
Systems Requirements

|| To record this tutorial, we will use-
* '''Ubuntu Linux OS ''' version 16.04
* '''eSim '''version 2.0
|-

||'''Show Slide:'''
Prerequisites

||To practice this tutorial,
*To create a circuit schematic and simulate the netlist file in '''eSim'''.
If not, watch the prerequisite '''eSim''' tutorials on this website.

|-
|| '''Show Slide:'''
Device Models

||The device model file begins with a dot model statement.
*'''mname''' indicates the model name like ''diode'' model ''1N4007'', ''1N534A''.
*'''Component type''' indicates the type of model used.

For example: ''D'' is used for ''Diode'',''M'' for ''MOSFET'',and

''NPN'' or ''PNP'' for ''BJT''.

*'''pname''' is the parameter name and
*'''pval''' is the parameter value.

|-
|| '''Show Slide:'''
Introduction

|| The model components are already added in '''eSim'''.

The model library files added using the '''Upload''' option will be saved in the User Libraries folder under '''deviceModelLibrary'''.

The model library files are used with the components present in '''eSim''' underscore '''Devices'''.

You can also refer to the spice models available in the '''Ngspice''' manual.

|-
|| '''System Computer:'''
Desktop icon

|| To launch '''eSim''', you need to double-click on the '''eSim''' icon on your '''Desktop'''.

|-
|| '''System Computer:'''
eSim startup window

|| I have already opened '''eSim'''.

|-
||Show Slide:
'''Code File'''

||Pause the video here.

Download the '''Schottky diode 1N5711''' library file from the '''Code file''' section available on this page.

Save it on your '''Desktop''' with dot '''lib''' extension.

|-
|| '''eSim Main Window:'''
Click on '''Model Editor'''

|| On the '''eSim''' window, click on the '''Model Editor''' button from the left toolbar.

In the previous tutorial, we have seen how to add a ''Device model'' using the '''New''' option.

Now, we will add a ''Device model'' library using the '''Upload''' option.

|-
|| '''Model Editor tab:'''
Click ''' Upload''' >>

Click on '''Desktop'''>>

click on '''Schottky_diode.lib''' >>

click '''Open'''

||On the ''' Model Editor''' tab, click on the '''Upload''' button.

I have already downloaded the ''Schottky diode IN5711'' model and saved it on my ''Desktop''.

Click on the '''Desktop'''.

Click on the '''Schottky''' dot '''lib''' file.

Click on the '''Open''' button.

|-
||'''Model Editor tab:'''
Type '''New Model Name''' as '''Schottky''' >>

click '''OK'''

||A pop-up window '''Model Name''' will appear.

In the '''Enter Model Library Name''', type New Model Name as '''Schottky'''.

Click on the '''OK''' button.

The ''device model'' '''Schottky''' and its '''xml''' file will be saved under the '''User libraries''' folder.

|-
||'''eSim Main Window:'''

||Let us simulate the characteristics of ''Schottky diode''.

We will open the example ''Diode Characteristics'' from the '''eSim''' ''Examples'' folder.

|-
||'''eSim Main Window:'''

Click on '''Open Project''' from the top toolbar >>

Double click on '''eSim-2.0''' >>

Click on '''Examples'''>>

select '''Diode_characteristics''' >>

click '''Open'''.

||We will open the '''Diode characteristic''' example from the '''Examples''' folder of '''eSim'''.

On the '''eSim'''' window, click on the '''Open Project''' button from the top menu.

Locate the directory where the '''eSim''' is installed.

Double click on the '''Examples''' folder.

Scroll down and select the '''Diode''' underscore '''characteristics'''.

Click on the '''Open''' button.

The '''Diode characteristics''' example is added to the '''eSim''' window under '''Projects'''.

|-
||'''eSim Main Window:'''
Select '''Diode_Characteristics''' under '''Projects'''>>

Click on the '''Open Schematic'''>>

Click '''Yes'''

||To see the schematic, select '''Diode characteristics'''.

Click on the '''Open Schematic''' button from the left toolbar.

It directs us to the ''schematic editor''.

|-
||'''eSim Schematic editor:'''
Press '''F1''' key.

||Press '''F1''' key to zoom in the schematic.

|-
||'''eSim Main Window:'''

Select '''Diode_characteristics'''>>

click on '''Convert Kicad to Ngspice'''

||Let us go back to the '''eSim''' window.

on the '''eSim''' window,select the '''Diode''' underscore '''characteristics'''.

Click on the '''Convert Kicad to Ngspice''' button from the left toolbar.

|-
||'''Kicad to Ngspice Converter:'''
'''Analysis''' Tab >>

Select '''DC'''

Enter the values.

||In the '''Analysis''' tab, Select '''DC'''.

Scroll down to enter values.

Enter '''Source 1''' as '''V1'''.

Enter '''Start''' as '''0'''.

Enter '''Increment''' as '''0.1'''.

Enter '''Stop''' as '''0.4'''.

|-
||'''Kicad to Ngspice Converter:'''
Source Details Tab:
Enter '''1''' for '''DC''' source '''V1'''.

||In the '''Source Details''' tab, enter ''' the value''' as '''1'''.

|-
||'''Kicad to Ngspice Converter:'''
'''Device Modeling''' Tab
Click on '''ADD'''>>

Double click on '''User Libraries''' folder>>

click on ''''Schottky.lib''' file>>

click '''Open'''.

||Skip the '''Ngspice Model''' tab.

Click on the ''''Device Modeling''' tab.

Click on the '''ADD''' button.

Double-click on the '''User Libraries ''' folder.

Select '''Schottky ''' dot '''lib''' file and

Click on the '''Open''' button.

|-
||'''Kicad to Ngspice Converter:'''
Click on '''Convert'''>>

Click '''OK'''

||On the '''Kicad to Ngspice''' tab, click on the '''Convert''' button.
Click on the '''OK''' button in the '''Information''' dialog box.

|-
||'''eSim Main Window:'''
Click on '''Simulation'''.

||Now, let us generate the ''plots''.
On the '''eSim''' window, click on the '''Simulation''' button from the left toolbar.

|-
||'''Ngspice Window:'''
Maximize the '''i(v_u1)''' ngspice plot.

Hover the mouse on '''X-axis''' to point '''voltage'''.

Hover the mouse on '''Y-axis''' to point '''current'''.

||This ''diode'' has a ''knee voltage'' or ''turn-on voltage'' of around '''0.2'''.

The ''forward current'' is '''95 microampere'''.

These ''diodes'' are used in ''power rectification'' applications.

Close the '''Ngspice''' ''terminal'' and ''plots''.

|-
||'''Python Plot Window:'''

Check '''In''' and '''Out''' node>>

click '''Plot'''

||In the '''Python''' ''plot'' window, check the '''In''' node and '''Out''' nodes.

Then click on the '''Plot''' button.

You can see the ''input'' and ''output'' plot.

Close the '''Python''' ''plot''.
