Deep Reinforcement Learning-Based Optimal Decoupling Capacitor Design Method for Silicon Interposer-Based 2.5-D/3-D ICs
HyunWook Park,Seongguk Kim,Youngwoo Kim,Joungho Kim,Junyong Park,Subin Kim,Kyungjun Cho,Daehwan Lho,Seungtaek Jeong,Shinyoung Park,Gapyeol Park,Boogyo Sim +11 more
TL;DR: A deep reinforcement learning (RL)-based optimal decoupling capacitor (decap) design method for silicon interposer-based 2.5-D/3-D integrated circuits (ICs) that provides an optimal decap design that satisfies target impedance with a minimum area.
Journal ArticleDOI
Signal Integrity Design and Analysis of Silicon Interposer for GPU-Memory Channels in High-Bandwidth Memory Interface
Kyungjun Cho,Youngwoo Kim,Hyunsuk Lee,Heegon Kim,Sumin Choi,Jinwook Song,Subin Kim,Junyong Park,Seongsoo Lee,Joungho Kim +9 more
TL;DR: It is shown that the proposed channels of the silicon interposer can successfully transfer data at a 2-Gb/s data rate and proposed concepts and solutions for the next-generation HBM interface with higher data rates up to 8 Gb/s are proposed.

TL;DR: A novel hybrid loop array (HLA) for low leakage electromagnetic field (EMF) level and high efficiency in a wireless high power transfer system using kHz range resonant frequency is proposed.
Proceedings ArticleDOI
Design optimization of high bandwidth memory (HBM) interposer considering signal integrity
Kyungjun Cho,Hyunsuk Lee,Heegon Kim,Sumin Choi,Youngwoo Kim,Jaemin Lim,Joungho Kim,Hyungsoo Kim,Yong-Ju Kim,Yunsaing Kim +9 more
TL;DR: Not only HBM interposer can be applied to achieve high bandwidth with a less signal distortion but also it can be designed on the basis of a limited routing area.
Proceedings ArticleDOI
Reinforcement Learning-Based Optimal on-Board Decoupling Capacitor Design Method
HyunWook Park,Junyong Park,Subin Kim,Daehwan Lho,Shinyoung Park,Gapyeol Park,Kyungjun Cho,Joungho Kim +7 more
TL;DR: The proposed reinforcement learning-based optimal on-board decoupling capacitor (decap) design method has successfully provided 37 optimal decap designs with 4 decaps assigned each and satisfied the required target impedance while minimizing the number of assigned decaps.
