Meeting ISO 26262 Requirements Using Tessent IC Test Solutions
By Mentor, a Siemens Business - 07 May, 2019 - Comments: 0

As the industry moves towards greater automation in vehicles, suppliers of the ICs used to drive the automotive electronic systems are rapidly adopting solutions to meet ISO 26262 requirements. The Tessent family of IC test products offers the highest defect coverage, in-system non-destructive memory test, hybrid ATPG/Logic BIST, and analog test coverage measurement. These technologies add up t... » read more

The Week In Review: Design
By Jesse Allen - 02 Nov, 2018 - Comments: 0

M&A GlobalFoundries formed Avera Semiconductor, a wholly-owned subsidiary focused on custom ASIC designs. While Avera will use its relationship with GF for 14/12nm and more mature technologies, it has a foundry partnership lined up for 7nm. The new company's IP portfolio includes high-speed SerDes, high-performance embedded TCAMs, ARM cores and performance and density-optimized embedded SR... » read more

Tessent Cell-Aware Test
By Mentor, a Siemens Business - 10 Sep, 2018 - Comments: 0

Tessent Cell-Aware ATPG is a transistor-level ATPG-based test methodology that achieves significant quality and efficiency improvements by directly targeting specific shorts; opens and transistor defects internal to each standard cell; resulting in significant reductions in defect (DPM) levels. Traditional scan patterns are created using fault models that are based on the logical operation of t... » read more

Digital IC Bring-Up With A Bench-Top Environment
By Matthew Knowles - 23 Aug, 2018 - Comments: 0

One of the hottest markets for IC today is artificial intelligence (AI). The designs for AI chips are also among the largest and most complex, with billions of transistors, thousands of memory instances, and complex design-for-test (DFT) implementations with unique bring up and debug requirements. At this point, the volume of new AI chips is relatively low, but time-to-market is of paramount im... » read more

The 2017 International Test Conference
By Jeff Dorsch - 09 Oct, 2017 - Comments: 0

Machine learning is a hot topic at many technical conferences this year. It will be true at the upcoming International Test Conference, which opens near the end of this month in Fort Worth, Texas. On Sunday, October 29, there are two tutorials devoted to machine learning. Monday, October 30, will have one tutorial related to the topic. The conference gets fully under way on Halloween, wit... » read more

Fault Simulation Reborn
By Brian Bailey - 23 Feb, 2017 - Comments: 0

Fault simulation, one of the oldest tools in the EDA industry toolbox, is receiving a serious facelift after it almost faded from existence. In the early days, fault simulation was used to grade the quality of manufacturing test vectors. That task was replaced almost entirely by [getkc id="173" comment="scan test"] and automatic test pattern generation (ATPG). Today, functional safety is cau... » read more

Analog Fault Simulation Challenges And Solutions
By Mentor, a Siemens Business - 28 Sep, 2016 - Comments: 0

The test time for digital circuit blocks in ICs has greatly decreased in the last 20 years, thanks to scan-based design-for-test (DFT), automatic test pattern generation (ATPG) tools, and scan compression. These technologies have greatly reduced the number of test vectors applied by automatic test equipment (ATE) while maximizing the coverage of a wide range of defect types. But for analog c... » read more

Putting Design Back Into DFT
By Brian Bailey - 25 Aug, 2016 - Comments: 0

Test always has been a delicate balance between cost and quality, but there are several changes happening in the industry that might cause a significant alteration in strategy. Part one of this two part series about [getkc id="47" comment="Design for Test (DFT)"] looked at changes in areas such as automotive, where built in self-test is becoming a mandated part of the design process. This co... » read more

Accelerating Design-For-Test Pattern Simulation
By Mentor, a Siemens Business - 23 Mar, 2016 - Comments: 0

The Veloce DFT App presents a true “left shift” improvement for a traditional chip design schedule that requires comprehensive gate-level simulations to develop ATPG, BIST, or functional patterns. It enables running complete patterns for DFT verification in a reasonable time to shorten the pattern development cycle. The Veloce DFT App fits seamlessly into the Veloce ecosystem, enabling a ho... » read more

Manufacturing Test Robustness
By Kiran Vittal - 11 Sep, 2014 - Comments: 0

The recent 6.0 earthquake near Napa California caused close to $50 million in damages to the wineries and property in the region. The San Francisco bay area is accustomed to earthquakes and hence structural engineers design buildings to bear high intensity earthquakes amongst other natural disasters. The damage to property would have been much higher if not due to the strict guidelines followed... » read more
