Integrating IFT enables two... » read more

Globally Asynchronous, Locally Synchronous Clocks


Typical IC clocking schemes are under stress in complex chip/chiplet designs, where multiple compute elements may not be operating at the same frequency consistently. Some cores may be powered down to save energy, or they may age at different rates, which in turn reduces performance. Lee Vick, vice president of strategic marketing at Movellus, explains why locally asynchronous clocking schemes ... » read more

Managing Reflections With Terminations


Have you heard recommendations to use a particular termination in particular situations for good signal integrity? Have you ever wondered how to incorporate terminations in your design? While there are typical use cases for various terminations, sometimes engineers use termination techniques based on a recommendation or assumption that may not work, or at least may not be optimal, for their par... » read more
