Show Slide:

Opening Slide

Welcome to the spoken tutorial on “Device Model Creation and Simulation using eSim”
Show Slide:

Learning Objectives

In this tutorial, using eSim we will learn how to-*
create device model
  • add or remove parameters of device model
  • save the device model
  • upload the external device model


Show Slide:

Systems Requirements

To record this tutorial, we will use-*
Ubuntu Linux 16.04
  • eSim version 1.1.2.


Show Slide:

Pre-requisites

To practice this tutorial, basic knowledge of analog and digital electronics is required.
System Computer:

Desktop icon

To launch eSim, double-click on the eSim icon on your desktop.
System Computer:

eSim startup window

The eSim window opens up.
eSim Main Window:

Creating device model library

Now let us create a device model library for a Diode.
eSim Main Window:

Click on >> Model Editor button

Click on the Model Editor button on the left tool-bar.
Model Editor Window:

Click >> New and Enter Model Name >> diode_test>>Click on OK

Click on New and type the Model name as Diode underscore test.

Click on OK.

Model Editor Window:

Select >> Diode category

Now select Diode category.
Highlight The basic parameters of a Diode is displayed.


We will keep the same for our diode model and edit it later.

Model Editor Window:

Click >> Save


Close model editor window

Click on the Save button at the top of the Model editor window.


Now close the Model editor window.

Let us run our Diode model using an example.
eSim Main Window:

Open >> Diode_Characteristics

Open the Diode_characteristic example from the Examples folder.


Please note:

Examples folder is located in eSim hyphen 1.1.2 folder which you have downloaded while installing.

Double Click >> Diode_characteristic in projects From Projects, double-click on the Diode_characteristics example.
eSim Main Window:
