In the complex journey of chip development, Post-Silicon Validation (PSV) plays a crucial role. Once the chip transitions from design blueprints to actual silicon wafers, PSV becomes the core process to verify whether it meets the expected functionality and performance. From a technical perspective, PSV primarily involves inputting various test vectors into the chip to … Read more
JTAG: The Core Interface for Chip Testability Design In the field of integrated circuit (IC) design, Design for Testability (DFT) is a key technology to ensure high reliability and yield in chip production. JTAG (Joint Test Action Group), as a standard test access interface, has become an important means for modern chips to implement DFT … Read more
Beijing Zhixin Technology is a long-established chip decryption company that can decrypt a wide range of chip models.After decryption, we can provide chip programming services and programming recommendations.Some customers have reported programming failures during mass production; is this an issue with the chip itself?Or is it a problem with the programmer?What other possibilities might there … Read more
Source: Semika Original Author: Semika Testing is an important means to ensure functionality and yield.Chip testing can be mainly divided into two parts.CP (chip probing) and FT (final test).Some chips will also undergo SLT (system level test).Additionally, some specific requirement chips need reliability testing. CP Testing CP (Chip Probing) testing, also known as wafer testing, … Read more
Original: Wolonghui Wolong Village Master Previously, some netizens asked what the JTAG principle is? Today, I will briefly explain it. JTAG is a debugging, testing, and online programming interface. JTAG (Joint Test Action Group) JTAG is an embedded debugging technology used to test chips. Once the circuit board is soldered, how can we ensure that … Read more
