Data Center Architectures In Flux


Data center architectures are becoming increasingly customized and heterogeneous, shifting from processors made by a single vendor to a mix of processors and accelerators made by multiple vendors — including system companies' own design teams. Hyperscaler data centers have been migrating toward increasingly heterogeneous architectures for the past half decade or so, spurred by the rising c... » read more

Unintended Coupling Issues Grow


The number of indirect and often unexpected ways in which one design element may be affected by another is growing, making it more difficult to ensure a chip — or multiple chips in a package — will perform reliably. Long gone are the days when the only way that one part of a circuit could influence another was by an intended wire connecting them. As geometries get smaller, frequencies go... » read more

Dissolving The Barriers In Multi-Substrate 3D-IC Assembly Design


Advanced packaging continues to promise improved form factor, cost, performance, and functionality compared to the traditional transistor scaling on SoCs. This is done by integrating multiple dies on top of a substrate (organic or silicon). Besides multiple dies, multiple substrates can typically exist in a 3D-IC assembly. In this case, the benefits of advanced packaging are taken to a whole ne... » read more

Addressing Library Characterization And Verification Challenges Using ML


At advanced process nodes, Liberty or library (.lib) requirements are more demanding due to design complexities, increased number of corners required for timing signoff, and the need for statistical variation modeling. This results in an increase in size, complexity, and the number of .lib characterizations. Validation and verification of these complex and large .lib files is a challenging task... » read more

Blog Review: Feb. 23


Synopsys' Varun Agrawal looks at four new technologies have emerged to support the demands on 5G networks and applications, the challenges in validating all of those technologies together, and what's needed to perform end-to-end testing effectively for 5G O-RAN SoCs. Siemens EDA's Ray Salemi points to how FPGA retargeting could help address supply chain difficulties and some of the challenge... » read more

Week In Review: Auto, Security, Pervasive Computing


Automotive Renesas and AVL Software and Functions are collaborating to support developers of automotive ISO 26262-compliant electronic control units (ECUs). Renesas sells automotive R-Car SoCs, RH850 automotive control MCUs, PMICs, and software for levels ASIL B to ASIL D of ISO26262, but even with automotive ISO26262 parts, ECU system development process is never plug and play. Functional saf... » read more

Experts at the Table: Semiconductor Engineering sat down to discuss the changes in design tools and methodologies needed for 3D-ICs, with Sooyong Kim, director and product specialist for 3D-IC at Ansys; Kenneth Larsen, product marketing director at Synopsys; Tony Mastroianni, advanced packaging solutions director at Siemens EDA; and Vinay Patwardhan, product management group director at Cadence... » read more

Blog Review: Feb. 16


Arm's Mark Nicholson explains the software side of the Morello project to implement a prototype security-focused architecture, presenting a high-level view of the software stacks and discussing the status and roadmap of a range of activities. Synopsys' Ron Lowman finds that as IoT technology and capabilities of portable devices expand, the deployment of 5G networks and interest in AI and aut... » read more

Improving PPA In Complex Designs With AI


The goal of chip design always has been to optimize power, performance, and area (PPA), but results can vary greatly even with the best tools and highly experienced engineering teams. Optimizing PPA involves a growing number of tradeoffs that can vary by application, by availability of IP and other components, as well as the familiarity of engineers with different tools and methodologies. Fo... » read more
