Double data rate chaining for synchronous DDR interfaces

TL;DR: In this paper, the receiving chip separately latches each half of the data received from the double data rate bus, each half is launched as soon as it is available; one on the normal chip cycle time and the other is launched from a Master (L1) latch a half cycle into the normal Chip cycle time.

Method for Replicating and Synchronizing a Plurality of Physical Instances with a Logical Master

TL;DR: In this paper, the authors propose a method for data design management of a master data set and at least one clone data set, and copying a master physical design data set into one or more physical instances.

Optimization method of integrated circuit design for reduction of global clock load and balancing clock skew

TL;DR: In this paper, a design methodology and algorithms for the computer aided design of integrated circuits having clock distribution networks is described in terms of reducing and balancing the load inside each clock sector, although the techniques may also be applied to balancing load between clock sectors.
