Mastering Design for Test Fundamentals
Every successful chip is a testable chip. Our asic design course provides a deep dive into the design for test fundamentals, giving you the foundational knowledge to ensure silicon quality and launch a successful career in VLSI.
The Fundamental Pillars of Design for Test (DFT)
Our asic online course breaks down the complex world of DFT into understandable, foundational concepts that every chip designer must know.
Observability & Controllability
Learn the two core principles of DFT: the ability to control the logic states inside a chip and observe the results at its pins.
Fault Models
Understand what you are testing for. We cover the fundamental fault models, like Stuck-at and Transition faults, that guide all DFT efforts.
Scan Design
Master the basic mechanism for testing any asic hardware. Learn how scan chains are inserted to provide access to a chip’s internal state.
ATPG (Automatic Test Pattern Generation)
Discover how specialized asic software is used to automatically generate the thousands of test patterns needed to detect manufacturing defects.
Built-In Self-Test (BIST)
Learn the fundamentals of BIST, a technique where the chip is designed to test itself, which is essential for memories and other regular structures.
Boundary Scan (JTAG)
Understand the JTAG standard, a fundamental technique used to test the connections between the asic and the asic board it’s mounted on.

A deep understanding of DFT is not just for specialists; it’s a required skill for all digital design and implementation engineers.
Required for Any Design Role
Even RTL designers must understand DFT fundamentals to write testable code. These principles are a core part of the entire asic development process.
The Gateway to Manufacturing
This is the language spoken between the asic design company and the asic manufacturer. A design without proper DFT is considered untestable and will be rejected.
Reduces Overall ASIC Cost
Good DFT practices are the most effective way to reduce the high asic cost associated with manufacturing test and debugging, saving companies millions.

FAQs About Design for Test Fundamentals
Your questions about this critical design discipline, answered.
Is DFT the same as verification?
No. Functional verification checks if the design’s logic is correct (e.g., does the adder add correctly?). Design for Test (DFT) adds hardware to the chip to help test for physical manufacturing defects after it’s made (e.g., is there a short circuit in the adder?).
What is a ‘fault’ in the context of DFT?
A fault is a model of a physical defect that could occur during manufacturing. The most common fundamental models are the ‘Stuck-at-0’ and ‘Stuck-at-1’ faults, where a logic gate is assumed to be permanently stuck at a low or high voltage.
Is this topic covered in a typical university asic design course?
University courses often introduce the basic theory, but our asic online program provides the deep, practical, hands-on experience with industry-standard asic software that is necessary to become a proficient DFT engineer.
