How to Successfully Design for Testing or DFT

Design for testing or DFT consists of IC design techniques that add testability features to a hardware product design. The added features make it easier to develop and apply manufacturing tests to the designed hardware.

The purpose of manufacturing tests is to validate that the product hardware contains no manufacturing defects that could adversely affect the product’s correct functioning. This article outlines the tips on how to successfully design for testing.

High Performance, Low Power, And Test: DFT’s Impact on System PPA And Safety

As test grows in importance, earlier integration is key. Safety-critical semiconductor applications have driven test squarely into the functional specification and system architecture stages of design. Without the proper consideration of test, high levels of coverage in short test times is impractical.

A poorly integrated test strategy results in negative impacts to system performance, power consumption, and in obtaining safety certification for the final product. This article highlights the impact of DFT on system power, performance, and area(PPA) and safety.

Design-For-Testability (DFT) Verified with Hardware Emulation

A DFT App enables execution of complete pattern sets for DFT verification in a reasonable time to shorten the pattern development cycle. Verification Consultant, Lauro Rizzatti, explores how an emulation session provides enough verification power to pull the DFT schedule within the time the project management has scheduled, thus accelerating the time to market, increasing the yield, and ultimately augmenting profits.

Smarter DFT Infrastructure and Automation Emerge as Keys to Managing DFT Design Scaling

The reality of DFT for large and complex SoCs has introduced new risk into design schedules. DFT teams end up in the critical path to tape out while waiting for portions of the design to be complete, and there are more DFT integration steps than ever before. The traditional approaches to DFT work on huge designs pose problems of repeatability and reliability.

With more DFT steps, the overall rate of success declines unless the rate of success at each step is extremely high. This article from Semiengineering explores how do you ensure an extremely high rate of success at each step in the DFT flow by adopting a smarter technology.

A Unified DFT Verification Methodology

In today’s fast-growing SoC, incomplete or ineffective DFT support due to poor specification or loose design practices can quickly become the critical path to making market windows and delivering products within cost restrictions.

This article highlights a unified DFT verification methodology, aimed at providing a complete, methodical and fully automated path from test specification to DFT closure and examine the benefits of this approach, looking at how this methodology can help bridge the widening gap between design and test.
