Using Test And Metrology Data For Dynamic Process Control


Advanced packaging is transforming semiconductor manufacturing into a multi-dimensional challenge, blending 2D front-end wafer fabrication with 2.5D/3D assemblies, high-frequency device characterization, and complex yield optimization strategies. These combinations are essential to improving performance and functionality, but they create some thorny issues for which there are no easy fixes. ... » read more

Screening For Known Good Interposers


Ensuring the quality of silicon and organic interposers is becoming harder as the number of signals passing through them continues to grow, fueled by more chiplets, higher processing demands, and more layers of devices assembled in a package. Interposers initially were viewed as relatively simple conduits. That perception has changed rather dramatically in recent years with the growing focus... » read more

Streaming Scan Network


Tessent Streaming Scan Network (SSN) is a system for packetized delivery of scan test patterns. It enables simultaneous testing of any number of cores with few chip-level pins, and reduces test time and test data volume. With SSN, DFT engineers have a true SoC DFT solution without compromises between implementation effort and manufacturing test cost. Challenges with DFT for complex SoCs The... » read more

No-Compromise Packetized Test Improves DFT Efforts


Design for Test (DFT) managers often must make difficult and sometimes costly trade-offs between test implementation effort and manufacturing test cost. The traditional method for evaluating these trade-offs has been to use hierarchical DFT methods in a divide-and-conquer approach. In hierarchical DFT efforts, all implementation, including pattern generation and verification, is done at the cor... » read more

DFT At The Leading Edge


Experts at the Table: Semiconductor Engineering sat down to discuss the rapidly changing landscape of design for testability (DFT), focusing on the impact of advancements in fault models, high-speed interfaces, and lifecycle data analytics, with Jeorge Hurtarte, senior director of product marketing in the Semiconductor Test Group at Teradyne; Sri Ganta, director of test products at Synopsys; D... » read more

Startup Challenges In A Changing EDA World


The Electronic Design Automation (EDA) industry is a mature industry, but it's also one that is constantly changing. Each process node and packaging technology advancement places new demands and constraints on existing tools. In addition, changing design problems and paradigms transform how design teams operate, and the goals they target. For a relatively small industry, EDA requires a dispr... » read more

Edge And IoT Security Turning A Corner


Security is beginning to improve for a wide range of IoT and edge devices due to better tools, the implementation of new standards and methodologies, and an increasing level of collaboration and communication across different market segments that in the past had little or no interaction. Until recently, many vendors in cost-sensitive markets offered the bare minimum of security. To make matt... » read more

How Software-Defined Vehicles Change Auto Chip Design


The shift to software-defined vehicles is changing nearly every aspect of automotive design, from what hardware is added into vehicles, when it gets added, and what gets left behind. Moving key features to software rather than hardware allows carmakers to bring new features to market faster, at a lower cost, and to modify those features more quickly. It is also expected to drive up the value... » read more

ISO 26262’s Importance Widens Beyond Automotive


The ISO 26262 standard, which has become a mainstay since the trend toward vehicle electrification really took root a decade ago, is starting to gain traction in markets outside of automotive chip and system design. At the center of this expansion is a focus on safety under a variety of conditions — extreme temperatures, unexpected vibration, or a collision that is unavoidable. This includ... » read more

Averting Hacks Of PCIe Transport Using CMA/SPDM


This paper describes the component measurement and authentication (CMA) and security protocol and data model (SPDM) flow used to establish the secure channels required for the transmission of encrypted packets. The various approaches, namely the symmetric and asymmetric flows, will be discussed in establishing a secure connection with the implementation of CMA/SPDM packets through data objects.... » read more
