For a multi-die IC, the chip-level clock synchronization problem that aims to establish a global clock signal across multiple functional dies is harder to achieve than its single-die counterpart. In this work, we investigate a process resilient solution for this problem by incorporating Delay-Locked Loops (DLLs). The basic idea is to insert a DLL (which can be generated by a DLL compiler) in each...
An 2.5D IC could be composed of a number of functional dies operating in locked steps defined by a global clock signal. However, the clock network design across multiple dies may not be trivial as the die-to-die interconnects used for relaying the clock signal from a source die to the other receiver dies could be unpredictable in their delays in real silicon. In this work, we propose a characterization-and-tuning...
A clock network in a 3D-IC is not only difficult to design, but also challenging to test. For high-performance designs with a rigorous clock-skew requirement, studies have shown that small defects in a clock tree network could lead to unexpected failures in the field and thus need to be identified during the manufacturing test. In this paper, we present a novel test method to determine if a clock...
