Atomic clocks to become even more accurate

by Laura Domela

The ultimate accessory in exact timekeeping — the atomic clock — is set to become even more precise, after ultrashort laser pulses were successfully transmitted across open air to help synchronize the “ticking” of new optical atomic clocks.

Keeping extremely precise time is not just a question of scientific achievement. It is a key to many modern technologies, fromGlobal Positioning Systems (GPS) to mobile phone networks and broadcasters’ transmitters. For GPS systems, an error of just one nanosecond, or a billionth of a second, would mean the location is about 12 inches (30 centimeters) off.

Quickly and accurately identify inter-domain leakage issues in IC designs

Sponsored by Siemens Digital Industries Software

Power domain leakage is a major IC reliability issue, often missed by traditional tools. This white paper describes challenges of identifying leakage, types of false results, and presents Siemens EDA’s Insight Analyzer. The tool proactively finds true leakage paths, filters out false positives, and helps circuit designers quickly fix risks—enabling more robust, reliable chip designs. With detailed, context-aware analysis, designers save time and improve silicon quality.
