Test More Complex For Cars, IoT


With increasing focus on safety-critical semiconductors—driven by ADAS, IoT, and security—functional safety concerns are going through the roof. Engineering teams are scrambling to determine how to conduct better in-field or online testing because test no longer can be an afterthought. This has been a common theme across the automotive ecosystem for the past few years, and as the automot... » read more

Devices Threatened By Analog Content?


As the amount of analog content in connected devices explodes, ensuring that the analog portion works properly has taken on a new level of urgency. Analog circuitry is required for interpreting the physical world and for moving data to other parts of the system, while digital circuitry is the fastest way to process it. So a sensor that gives a faulty reading in a car moving at high speed or ... » read more

Addressing Test Time Challenges


Unit test time on automated test equipment (ATE) is one of the major components that affects the total cost of manufacturing for semiconductor suppliers. The test programs for each unit can be comprised of thousands of parametric and functional tests that are performed to screen out defective units or dies. However, tester time is expensive, so suppliers are always looking for ways to reduce th... » read more

ATO 2017: Driven by Necessity


In the aerospace and defense industry, reducing release cycles and preventing program delays have become increasingly difficult. In automotive, consumer demands are driving up test complexity and introducing new costs in areas like infotainment. In response, test managers must find affordable ways to incorporate RF testing for wireless signals and machine vision testing for assisted parking to ... » read more

Logic Analyzers Never Die


Logic analyzers, long a mainstay of chip design, are finding new demand for IoT devices—and frequently in different forms than in the past. Once associated with big, bulky benchtop instruments, this technology has evolved significantly over the past 40 years. In some cases it has been moved into software, where the measurement results are more likely to be viewed upon a laptop screen or a ... » read more

Standardizing Platforms From Characterization To Production


In 1983, the first commercial mobile phone retailed for $3995, almost $10,000 in today’s economy. It supported a single band, weighed almost a kilogram, and was about the size of a brick. Two decades later, a quad-band “world phone” costs a few hundred dollars. Even a basic mobile phone that supports over 20 cellular bands, in addition to Bluetooth, Wireless LAN, and GPS technology, ... » read more

Transistor-Level Defect Diagnosis


Each new semiconductor process node represents exciting opportunities for suppliers of design, manufacturing, test, and failure analysis solutions. A new process means new challenges to solve, and hopefully more money to be made. On the flip side, whenever solutions that address these new challenges are presented, we seldom hear how useful these are to more mature process nodes. One technology ... » read more

Expose Transistor-Level Yield Limiters With Cell-Aware Diagnosis


Cell-aware diagnosis is a new and effective method to perform transistor-level diagnosis to identify defects inside standard cells. It leverages fault models derived from analog simulation and uses a fail data collection and diagnosis flow identical to that of traditional diagnosis. Cell-aware diagnosis in Tessent Diagnosis is the result of over 10 years of research in cell-aware test and was d... » read more

When Exposed To IoT, Big Iron ATE Will Rust


When the first “smart” refrigerators were released in the early 2000s, consumers weren’t sure what to do with them. When Nest released the smart thermostat, though, a revolution happened. Humans were taken out of the loop because the thermostat learned on its own about desired temperature and how quickly it could cool or heat a house. And it could synchronize all of this better than a hum... » read more

Formal’s Roadmap


Formal verification has come a long way in the past five years as it focused on narrow tasks within the verification flow. Semiconductor Engineering sat down to discuss that progress, and the future of formal technologies, with [getperson id="11306" comment="Raik Brinkmann"], president and CEO of [getentity id="22395" e_name="OneSpin Solutions"]; Harry Foster, chief verification scientist at [g... » read more
