However, with the growing PDN size and increasing scenarios to be validated, it becomes very time- and resource-consuming to conduct full-stack PDN simulation to check the power integrity for different test vectors. Recently, various works have proposed machine learning\u2013based methods for PDN power integrity prediction, many of which still suffer from large training overhead, inefficiency, or non-scalability. Thus, this article proposed an efficient and scalable framework for the worst-case power integrity prediction, which can handle general tasks including dynamic noise prediction and bump current prediction. The framework first reduces the spatial and temporal redundancy in the PDN and input current vector and then employs efficient feature extraction as well as a novel convolutional neural network architecture to predict the worst-case power integrity. Experimental results show that the proposed framework consistently outperforms the commercial tool and the state-of-the-art machine learning method with only 0.63\u20131.02% mean relative error and 25\u201369\u00d7 speedup for noise prediction and 0.22\u20131.06% mean relative error and 24\u201364\u00d7 speedup for bump current prediction.<\/jats:p>","DOI":"10.1145\/3564932","type":"journal-article","created":{"date-parts":[[2022,10,3]],"date-time":"2022-10-03T12:26:14Z","timestamp":1664799974000},"page":"1-19","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":9,"title":["Worst-case Power Integrity Prediction Using Convolutional Neural Network"],"prefix":"10.1145","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5993-7776","authenticated-orcid":false,"given":"Xiao","family":"Dong","sequence":"first","affiliation":[{"name":"Zhejiang University, Hangzhou, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4947-2917","authenticated-orcid":false,"given":"Yufei","family":"Chen","sequence":"additional","affiliation":[{"name":"Zhejiang University, Hangzhou, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6493-0950","authenticated-orcid":false,"given":"Jun","family":"Chen","sequence":"additional","affiliation":[{"name":"Giga Design Automation Co., Ltd, Shenzhen, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4204-8144","authenticated-orcid":false,"given":"Yucheng","family":"Wang","sequence":"additional","affiliation":[{"name":"Giga Design Automation Co., Ltd, Shenzhen, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2637-4943","authenticated-orcid":false,"given":"Ji","family":"Li","sequence":"additional","affiliation":[{"name":"Giga Design Automation Co., Ltd, Shenzhen, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6272-8660","authenticated-orcid":false,"given":"Tianming","family":"Ni","sequence":"additional","affiliation":[{"name":"Anhui Polytechnic University, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9160-048X","authenticated-orcid":false,"given":"Zhiguo","family":"Shi","sequence":"additional","affiliation":[{"name":"Zhejiang University, Hangzhou, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4656-9545","authenticated-orcid":false,"given":"Xunzhao","family":"Yin","sequence":"additional","affiliation":[{"name":"Zhejiang University, Hangzhou, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2610-7522","authenticated-orcid":false,"given":"Cheng","family":"Zhuo","sequence":"additional","affiliation":[{"name":"Zhejiang University, Hangzhou, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2023,5,17]]},"reference":[{"key":"e_1_3_1_2_2","doi-asserted-by":"publisher","DOI":"10.1109\/MDT.2007.79"},{"key":"e_1_3_1_3_2","first-page":"2473","article-title":"PAM: A piecewise-linearly-approximated floating-point multiplier with unbiasedness and configurability","author":"Chen Chuangtao","year":"2021","unstructured":"Chuangtao Chen, Weikang Qian, Mohsen Imani, Xunzhao Yin, and Cheng Zhuo. 2021.
