Synchronous Die-to-Die Signaling Using Aeonic Connect


This paper presents a system providing accurate clock alignment for on-die and die-to-die synchronous circuits. A low-frequency reference clock provides an accurate timing reference with low power consumption, while distributed delay lines align the endpoints of loosely constrained clock trees. For on-die clocks, this synchronization strategy severs the traditional relationship between power an... » read more

Pinpointing Timing Delays in Complex SoCs


Telemetry circuits are becoming a necessity in complex heterogeneous chips and packages to show how these devices are behaving post-production, but fusing together relevant data to identify the sources of problems adds its own set of challenges. In the past, engineering teams could build margin into chips to offset any type of variation. But at advanced nodes and in advanced packages, tolera... » read more
