Introduction
This is an introduction to the ESD Simulation operations, and this tutorial.
Overview
Electro Static Discharge (ESD) is one of the main causes of hardware failure of an electronic
system. Man with charge touching a cellphone, or a cable with charge connecting to the USB port of
a computer may lead to unexpected large current going through a system working under normal
condition, resulting in damages or system operation error.
To prevent such issues from unexpected current or voltage, an electronic design needs to have
protection devices integrated. To ensure a system can stand the ESD impact, designers need to
test the actual design or system in a standard environment with specially designed stimulus (an
ESD gun) and configuration, based on susceptibility standard.
There have been increasing demands of examining a system with ESD effect and implementing
protection schemes in a software environment. This will help find ESD problems in a system in the
early design stages, optimize the application of protection devices, and therefore reduce the risk of
failed products.
The ESD Simulation workflow in SPEED2000 is a practical simulation solution to help the
designers test a product in a software environment. It contains the following functions:
Providing default ESD gun model circuit for you to inject ESD current that follows the standard
Specifying the necessary steps to observe ESD phenomenon on a board/package design
Setting up ESD protections
