Nanosheet field-effect transistors flow current through multiple stacks of silicon that are completely surrounded by the transistor gate. The Shape of Things to Come: Nanosheet field-effect transistors flow current through multiple stacks of silicon that are completely surrounded by the transistor gate. The design reduces avenues for current to leak through and boosts the amount of current the device can drive. Image: IBM

The modern microprocessor is among the world’s most complex systems, but at its heart is a very simple, and we think beautiful, device: the transistor. There are billions of them in a microprocessor today, and they are nearly all identical. So improving the performance and boosting the density of these transistors is the most straightforward way to make microprocessors—and the computers they power—work better.

Design for Functional Safety & Reliability with new FMEDA Database

Component Reliability Database drives efficiency and accuracy in FMEDA results

Design for Functional Safety & Reliability with new FMEDA Database

Failure Modes, Effects, and Diagnostics Analysis (FMEDA) is popular for predicting safety and reliability during design. FMEDA results, however, are only as good as the failure rate data used in the calculations. A new component reliability database (CRD) improves accuracy, reduces engineering, identifies unforeseen failure modes, and enables better decision-making.
