|00:01
| Welcome to the spoken tutorial on '''Uploading a Spice Device Model''' in '''eSim'''.

|-
|00:08
|In this tutorial, using '''eSim''' we will learn -

To create a '''Schottky Diode''' using the '''Upload''' option.

|-
|00:17
| To record this tutorial, we will use-

'''Ubuntu Linux OS ''' version 16.04

'''eSim '''version 2.0

|-
|00:28
|To practice this tutorial, you should know to

create a '''circuit schematic''' and

'''simulate''' the '''netlist''' file in '''eSim'''.

|-
|00:39
|If not, watch the prerequisite '''eSim''' tutorials on this website.

|-
|00:45
|The '''device model''' file begins with a '''dot model''' statement.

|-
|00:50
|'''mname''' indicates the '''model''' name like '''diode model 1N4007, 1N534A'''.
'''Component type''' indicates the '''type''' of '''model''' used.

|-
|01:05
|Example: '''D''' is used for '''Diode''','''M''' for '''MOSFET''',and
'''NPN''' or '''PNP''' for '''BJT'''.

|-
|01:15
|'''pname''' is the '''parameter''' name and '''pval''' is the '''parameter''' value.

|-
|01:22
|The '''model library''' files added using the '''Upload''' option will be saved in the '''User Libraries''' folder under '''device Model Library''' directory.

|-
|01:35
|The '''model library''' files are used with the '''components''' present in '''eSim underscore Devices'''.

|-
|01:44
|You can also refer to the '''spice models''' available in the '''Ngspice''' manual.

|-
|01:51
| To launch '''eSim''', you need to double-click on the '''eSim''' icon on your '''Desktop'''.

|-
|01:58
|I have already opened '''eSim'''. Pause the video here.

|-
|02:02
|Download the '''Schottky diode 1N5711 library''' file from the '''Code file''' section available on this page.

|-
|02:13
|Save it on your '''Desktop''' with '''dot lib''' extension.

|-
|02:19
| On the '''eSim''' window, click on the '''Model Editor''' button from the left toolbar.

|-
|02:26
|In the previous tutorial, we have seen how to add a '''Device model''' using the '''New''' option.

|-
|02:35
|Now, we will add a '''Device model library''' using the '''Upload''' option.

|-
|02:42
|On the ''' Model Editor''' tab, click on the '''Upload''' button.

|-
|02:47
|I have already downloaded the '''Schottky diode IN5711 model''' and saved it on my '''Desktop'''.

|-
|02:57
|Click on the '''Desktop'''. Click on the '''Schottky dot lib''' file.

|-
|03:04
|Click on the '''Open''' button.

|-
|03:07
|A pop-up window '''Model Name''' will appear.

|-
|03:11
|In the '''Enter Model Library Name''', type new model name as '''Schottky'''. Click on the '''OK''' button.

|-
|03:21
|The '''device model Schottky''' and its '''xml''' file will be saved under the '''User libraries''' folder.

|-
|03:30
|Let us '''simulate''' the '''characteristics''' of '''Schottky diode'''.

|-
|03:35
|We will open the example '''Diode Characteristics''' from the '''eSim Examples''' folder.

|-
|03:43
|On the '''eSim''' window, click on the '''Open Project''' option from the top menu.

|-
|03:50
|Locate the '''directory''' where the '''eSim''' is installed.

|-
|03:55
|Click on the '''Examples''' folder.

|-
|03:59
|Scroll down and select the '''Diode underscore characteristics'''.

|-
|04:04
|Click on the '''Open''' button. The '''Diode characteristics''' example is added to the '''eSim''' window under '''Projects'''.

|-
|04:14
|To see the '''schematic''', select '''Diode characteristics'''.

|-
|04:19
|Click on the '''Open Schematic''' button from the left toolbar. It directs us to the '''schematic editor'''.

|-
|04:28
|Press '''F1''' key to zoom in the '''schematic'''.

|-
|04:33
|Let us go back to the '''eSim''' window.

|-
|04:37
|On the '''eSim''' window,select the '''Diode underscore characteristics'''.

|-
|04:43
|Click on the '''Convert Kicad to Ngspice''' button from the left toolbar.

|-
|04:49
|In the '''Analysis''' tab, select '''DC'''.

|-
|04:53
|Scroll down to enter values.

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

|-
|05:01
|Enter '''Start''' as '''0'''.

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

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

|-
|05:12
|In the '''Source Details''' tab, enter the value as '''1'''.

|-
|05:17
|Skip the '''Ngspice Model''' tab.

|-
|05:20
|Click on the '''Device Modeling''' tab.

|-
|05:24
|Click on the '''ADD''' button. Double-click on the '''User Libraries ''' folder.

|-
|05:31
|Click on '''Schottky dot lib''' file and click on the '''Open''' button.

|-
|05:37
|On the '''Kicad to Ngspice''' tab, click on the '''Convert''' button.

|-
|05:43
|Click on the '''OK''' button in the '''Information''' dialog box.

|-
|05:48
|Now, let us generate the '''plots'''.

|-
|05:51
|On the '''eSim''' window, click on the '''Simulation''' button from the left toolbar.

|-
|05:58
|The '''diode''' has a '''knee voltage''' or '''turn-on voltage''' of around '''0.2'''.

|-
|06:05
|The '''forward current''' is '''95 microampere'''.

|-
|06:10
|These '''diodes''' are used in '''power rectification''' applications. Close the '''Ngspice terminals''' and '''plots'''.

|-
|06:20
|In the '''Python plot''' window, check the '''In''' and '''Out''' nodes.

|-
|06:25
|Then click on the '''Plot''' button.

|-
|06:29
|You can see the '''input''' and '''output plot'''. Close the '''Python plot'''.

|-
|06:36
|Let us now summarise.

|-
|06:39
|In this tutorial, we learnt to create

'''Schottky Diode''' using '''Upload''' option.
