Gaps Emerge In Test And Analytics


Sensor and process drift, increased design complexity, and continued optimization of circuitry throughout its lifetime are driving test and analytics in new directions, requiring a series of base comparisons against which equipment and processes can be measured. In the design world this type of platform is called a digital twin, but in the test world there is no equivalent today. And as more... » read more

Testing In Context Gaining Ground


Testing in context is beginning to gain wider appeal as chip complexity increases, and as ICs are deployed in more safety-critical and mission-critical applications. While design in context has been the norm for SoCs for some time, a similar approach in test has been slow going. Cell-aware testing technology was first described a decade ago, and since then its adoption has been modest. But w... » read more

Different Ways To Improve Chip Reliability


A push toward greater reliability in safety- and mission-critical applications is prompting some innovative approaches in semiconductor design, manufacturing, and post-production analysis of chip behavior. While quality over time has come under intensive scrutiny in automotive, where German carmakers require chips to last 18 years with zero defects, it isn't the only market demanding extende... » read more

Test In New Frontiers: Flexible Circuits


Test is becoming increasingly complicated as new technologies such as flexible electronics begin playing mission-critical roles in applications where electronics have little or no history. Although flexible circuitry has been around for while, testing needs to catch up as these circuits are deployed across a variety of markets where conditions may be extreme. In many cases, sensors for monit... » read more

Leveraging Data In Chipmaking


John Kibarian, president and CEO of PDF Solutions, sat down with Semiconductor Engineering to talk about the impact of data analytics on everything from yield and reliability to the inner structure of organizations, how the cloud and edge will work together, and where the big threats are in the future. SE: When did you recognize that data would be so critical to hardware design and manufact... » read more

Reducing Costly Flaws In Heterogeneous Designs


The cost of defects is rising as chipmakers begin adding multiple chips into a package, or multiple processor cores and memories on the same die. Put simply, one bad wire can spoil an entire system. Two main issues need to be solved to reduce the number of defects. The first is identifying the actual defect, which becomes more difficult as chips grow larger and more complex, and whenever chi... » read more

Shrinking AV’s 1 Billion Test Miles


There is still no answer to how many miles an autonomous vehicle needs to drive before it's proven safe. But some AV developers and test companies are hoping to ease the burden a bit with automation that makes millions of real and simulated miles of road testing simpler to implement, supported by standards that make it easier to create and trade simulation scenarios. The goal is to reduce th... » read more

Testing Against Changing Standards In Automotive


The infusion of more semiconductor content into cars is raising the bar on reliability and changing the way chips are designed, verified and tested, but it also is raising a lot of questions about whether companies are on the right track at any point in time. Concerns about liability are rampant with autonomous and assisted driving, so standards are being rolled out well in advance of the te... » read more

How Hardware Can Bias AI Data


Clean data is essential to good results in AI and machine learning, but data can become biased and less accurate at multiple stages in its lifetime—from moment it is generated all the way through to when it is processed—and it can happen in ways that are not always obvious and often difficult to discern. Blatant data corruption produces erroneous results that are relatively easy to ident... » read more

Test On New Technology’s Frontiers


Semiconductor testing is getting more complicated, more time-consuming, and increasingly it requires new approaches that have not been fully proven because the technologies they are addressing are so new. Several significant shifts are underway that make achieving full test coverage much more difficult and confidence in the outcome less certain. Among them: Devices are more connected an... » read more
