Sorting is a fundamental problem in computer science and has been studied extensively. Thus, a large variety of sorting methods exist for both software and hardware implementations. For the latter, there is a trade-off between the throughput...
Statistical Rare-Event Analysis and Parameter Guidance by Elite Learning Sample Selection
Yue Zhao, Taeyoung Kim, Hosoon Shin, Sheldon X.-D. Tan, Xin Li, Haibao Chen, Hai Wang
Article No.: 56
Accurately estimating the failure region of rare events for memory-cell and analog circuit blocks under process variations is a challenging task. In this article, we propose a new statistical method, called EliteScope, to estimate the...
Construction of Reconfigurable Clock Trees for MCMM Designs Using Mode Separation and Scenario Compression
Rickard Ewetz, Cheng-Kok Koh
Article No.: 57
The clock networks of many modern circuits have to operate in multiple corners and multiple modes (MCMM). We propose to construct mode-reconfigurable clock trees (MRCTs) based on mode separation and scenario compression. The technique of scenario...
