FuSa Flow For Achieving An ASIL-C Safety Architecture


ISO 26262, titled “Road vehicles – Functional safety,” is an international standard for the functional safety of electrical and electronic systems in road vehicles. First published in 2011 and revised in 2018, ISO 26262 adapts the broader IEC 61508 standard for automotive applications. The ISO 26262 standard underscores the importance of achieving specific random hardware failure rate tar... » read more

Questa One Avery VIP: Accelerated Confidence In Complex Protocol Verification


In today’s rapidly advancing digital landscape, the role of functional verification has never been more critical. As systems become increasingly complex, ensuring their reliability and performance poses significant challenges for both design and verification engineers. The stakes are high; verification failures can lead to costly recalls, safety risks, and damage to brand reputation. The late... » read more

Finding And Fixing Leakage Between Power Domains


While there are many forms of current leakage in semiconductors, one especially nefarious type of leakage happens between power rails or power domains. Finding inter-domain leakage is vitally important for design reliability, especially in mixed power system design, but it is a known weakness of traditional electronic design automation (EDA) tools. Specialized EDA tools are needed to accurately... » read more

Using High-Quality Deterministic Patterns For In-System/In-Field Testing


Logic BIST (LBIST) is a well-stablished traditional solution for meeting automotive testing standards. However, using pseudo-random LBIST patterns can be challenging when trying to achieve high-quality testing due to the increased complexity of designs. The growing amount of electronic content, along with the shift toward fully autonomous vehicles, demands stringent testing requirements. In-... » read more

A Guide To SDC-Based Timing Intent Verification With Questa One


As semiconductor designs continue to grow in complexity and timing margins become increasingly constrained, achieving predictable timing closure has evolved from a best practice into a critical requirement for first-pass silicon success. At the heart of this process lies the timing constraint file, i.e., the SDC (Synopsys Design Constraints), which defines the intended timing behavior of the de... » read more

Thermo-Mechanical Stress On Active Chiplets In A 3D-IC Heterogeneous Package Assembly


The move to heterogeneous multi-chip/chiplet products improves yield, performance and modularity while reducing power and overall product footprint. However, this shift to heterogeneous assembly also introduces new complexities that can influence chip warpage and circuit behavior due to thermo-mechanical stress impacts. In heterogeneous 3D IC architectures, the interaction between the chips ... » read more

Intent Meets Implementation


Power efficiency has become a must-have in today’s ASIC and SoC designs. It’s no longer just about squeezing out more performance. It’s about doing so without draining the battery, wasting energy or overheating the system. Whether the chip is headed for a smartphone, a server rack in an AI datacenter or the control system of an autonomous vehicle, managing power wisely is as critical as m... » read more

Shifting Left With DFT To Optimize Productivity, Testability, And Time-To-Market


This paper discusses one of the Siemens EDA shift-left strategies in the RTL-to-signoff flow: shift-left design-for-test (DFT). Tessent RTL Pro software automates the analysis and insertion of Tessent VersaPoint test point technology, LBIST-OST test points, dedicated scan wrapper cells and x-bounding logic as behavioral code at the RTL level. Tessent RTL Pro builds on Tessent’s market-leading... » read more

HyperLynx


You gain the full power of HyperLynx when it is fully integrated as part of the Xpedition PCB design flow. Yet, it also interfaces with most PCB layout tools, allowing any engineer to quickly import and set up their PCB designs for analysis, regardless of their existing toolset. And because its progressive verification methodology analyzes a design in stages, HyperLynx locates issues earlier an... » read more

A Novel Approach For HW/SW Co-Verification


The complexity of system on chips (SoCs) continues to grow rapidly. Accordingly, new standards and methodologies are introduced to overcome these verification challenges. The Portable Test and Stimulus Standard (PSS) from Accellera is one of the standard examples used to pursue such challenges. In this paper we will show a methodology to use PSS to orchestrate the process of HW/SW co-verificati... » read more
