How much DFT is required as per standard ?

Question

Accepted Answer

The amount of DFT required as per standard varies depending on the specific industry and project requirements.

The required amount of DFT (Design for Testability) is determined by industry standards and project specifications.
Different industries may have different standards for DFT.
The complexity and size of the project also influence the amount of DFT required.
DFT techniques include scan chains, built-in self-test (BIST), boundary scan, and more.
The goal of DFT is to ensure efficient testing and fault coverage during manufacturing and in-field operation.
Examples of DFT standards include IEEE 1149.1 (JTAG) for boundary scan and IEEE 1687 (IJTAG) for embedded instruments.
DFT requirements should be defined and agreed upon during the design phase of a project.
