The considered eye metric is computed through a simple and effective procedure based on a polygonal approximation of the clean inner eye area. Least squares support vector machine regression is used, yielding a fast and accurate surrogate model of the link, providing a quantitative information of the data communication quality. The generated model turns out to be a parametric description which is used in the framework of stochastic analysis and uncertainty quantification, allowing to take into account the effects of the variation of the electrical and geometrical parameters of the link. The accuracy and convergence of the proposed machine learning solution are thoroughly discussed.","PeriodicalId":281134,"journal":{"name":"2023 IEEE 27th Workshop on Signal and Power Integrity (SPI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123998104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Eye diagrams have revealed to be a useful tool for assessing the quality of a channel and as such, should include the effects of crosstalk.

Temperature and humidity variations were applied to three printed circuit board stack-ups fabricated with different base materials and copper foils. The insertion loss was measured for the environment changes and compared between the boards. An increase in the insertion loss profile was observed for temperature and humidity variations in all the boards.","PeriodicalId":281134,"journal":{"name":"2023 IEEE 27th Workshop on Signal and Power Integrity (SPI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133420642","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By employing the stochastic testing method, we succeed in limiting the number of calls to the full-wave electromagnetic field solver at the core of the system. Additionally, the computationally burdensome solution of the eigenvalue problem is eased by reducing its order through projection on an appropriate basis. The resulting two-step accel-eration leads to an effective approach to assess the effect of line edge roughness on the characteristics of interconnects. The novel framework is applied to a rough rectangular waveguide and a microstrip.","PeriodicalId":281134,"journal":{"name":"2023 IEEE 27th Workshop on Signal and Power Integrity (SPI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127511350","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The stub resonance is predicted analytically with acceptable error, and the stub notch resonance is extracted from full-wave simulations for several cases of wipe length. A length limit is derived in order to keep the notch frequency of the resonating stub outside the usable bandwidth practically set at 0.75 times the baud rate for the PAM 4 type of modulation.","PeriodicalId":281134,"journal":{"name":"2023 IEEE 27th Workshop on Signal and Power Integrity (SPI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114139867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, accurate prediction of PDN noise continues to be critical to the design process. In this paper, we will touch upon a range of strategies for verifying PDN noise simulation results.

Nevertheless, heat is still generated, and this directly affects the reliability of these solid-state light (SSL) devices. In order to decrease the operating temperature, these LEDs can be assembled on metal core printed circuit boards (MCPCBs). However, in applications where stability/lifetime is a critical parameter, such as space applications, diamond plates may be considered. These plates are available from manufacturers with metallized tracks for direct assemblage of surface mount devices (SMD). In order to evaluate the impact of the board on SSL reliability, high power Cree LEDs were assembled on MCPCB and diamond plates. The case temperature was measured for different current ratings and the life-time increase induced by the diamond plate was estimated based on the calculation of the acceleration factor (AF). Diamond plates were shown to have a big impact on the life-time; for nominal current level, and depending on the activetion energy of the aging processes, the LED assembled on the MCPCB will age 2.5-8.8 times faster than the one assembled on the diamond plate. For high current ratings the spectrum radiated by the LED assembled on the diamond plate was also shown to be more stable than the one on the MCPCB.","PeriodicalId":281134,"journal":{"name":"2023 IEEE 27th Workshop on Signal and Power Integrity (SPI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127999757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
