Scan latch

WebAbstract: Scan design, being part of the most commonly practiced form of Design for Testability (DFT) has been developed to enable software based diagnosis for scan chain failures. Tessent Diagnosis helps to narrow down the reported failures to a suspected failing chain [1] - [5]. Unfortunately, scan chains can consist of hundreds to thousands of … WebMay 6, 2024 · The boundary scan test architecture incorporates boundary-scan (logic) cells placed between the IC’s core logic and the I/O pins or balls (the chip’s boundary). The cells …
