The Cost Of Accuracy


How accurate does a system need to be, and what are you willing to pay for that accuracy? There are many sources of inaccuracy throughout the development flow of electronic systems, most of which involve complex tradeoffs. Inaccuracy leaves an impact on your design in ways you are not even aware of, hidden by best practices or guard-banding. EDA tools also inject some inaccuracy. As the i... » read more

Ultra-Low-Power SAR ADC in 22 nm FD-SOI Technology Using Body-Biasing


Today’s sensor applications show a rising demand on miniaturized autonomous sensors nodes with extreme requirements on power dissipation. One core functionality of these sensor nodes is the conversion of analog sensor signals to digital data for post processing and data communication. In this work a 11-bit Successive Approximation Register (SAR) ADC with minimized power dissipation is develop... » read more

How To Improve Analog Design Reuse


Digital circuit design is largely automated today, but most analog components still are designed manually. This may change soon. As analog design grows increasingly complex and error-prone, design teams and tool vendors are focusing on how to automate as much of the design of analog circuits as possible. Analog design is notoriously difficult and varied. It can include anything from power ma... » read more

Interaction Of Hard IP And Chip-Package


Current and future customer-specific circuit development requires an increasing number of different interfaces, such as for memory (DDR3, DDR4, LPDDR3, LPDDR4, etc.), radio interfaces (Bluetooth, NBIoT, etc.) or high-speed LVDS/SERDES interfaces (DisplayPort, Ethernet, USB, etc.). For customer-specific circuit projects, these components are frequently purchased as hard IP because the developmen... » read more

Carmakers To Chipmakers: Where’s The Data?


The integration of electronics into increasingly autonomous vehicles isn't going nearly as smoothly as the marketing literature suggests. In fact, it could take years before some of these discrepancies are resolved. The push toward full autonomy certainly hasn't slowed down, but carmakers and the electronics industry are approaching that goal from very different vantage points. Carmakers and... » read more

Functional Safety And Requirements Engineering


Currently, dramatically increasing design costs are being reported for safety-critical applications. This is caused by additional necessary actions to implement and verify functional safety requirements. Such requirements are appearing with a clearly increasing tendency in the area of mobility (automotive, transport, aerospace) as well as in industrial automation and medical technology. In many... » read more

Power Delivery Affecting Performance At 7nm


Complex interactions and dependencies at 7nm and beyond can create unexpected performance drops in chips that cannot always be caught by signoff tools. This isn't for lack of effort. The amount of time spent trying to determine if an advanced-node chip will work after it is fabricated has been rising steadily for several process nodes. Additional design rules handle everything from variation... » read more

Temperature Reduction on a High-Power Thermal Demonstrator


High-power applications in microelectronic devices and systems is a crucial and severe issue that may cause elevated thermal and thermomechanical phenomena and finally lead the fabricated system to degradation, limitation of its performance, or even failure and destruction of its features. In specific applications, such as those found in the industry and the automotive sector, the power pro... » read more

Aging In Advanced Nodes


Semiconductor Engineering sat down to discuss design reliability and circuit aging with João Geada, chief technologist for the semiconductor business unit at ANSYS; Hany Elhak, product management director, simulation and characterization in the custom IC and PCB group at Cadence; Christoph Sohrmann, advanced physical verification at Fraunhofer EAS; Magdy Abadir, vice president of marketing at ... » read more

Mission Profiles


In the field of electronic systems, the mission profile has been one of the key concepts since the start of the scientific examination of the subject of reliability. Its exact meaning varies with time and the industry using it. In particular, over the course of increasing digitalization and networking in the context of IoT and the opportunities resulting from this, the subject of mission profil... » read more
