It’s not the smallest transistor out there, but the boffins at IBM have constructed the tiniest carbon nanotube transistor to date. It’s nine nanometers in size, making it one nanometer smaller than the presumed physical limit of silicon transistors. Plus, it consumes less power and is able to carry more current than present-day technology.

Want early design analysis without simulation?

Sponsored by Siemens Digital Industries Software

Traditional verification methods are failing today's complex IC designs, which require a proactive, early-stage analysis approach. A shift-left methodology addresses IP block integration challenges and the limitations of traditional simulation and ERC tools. Insight Analyzer detects hard-to-find leakage issues across power domains, enabling early analysis without full simulation. Identify inefficiencies earlier to reduce rework, improve reliability, and enhance power performance.
