With careful engineering utilizing cutting-edge full-wave field-solver software: Momentum (MOM) [1], EMpro (FDTD) [2] along with a hardware boost with heterogeneous massive CPU/GPU parallel processing (CUDA) technology [3], we can move the EMI teams from the back-end black-magic to a successful cost-effective front-end design.

This result applies to ranges from DC to frequencies for which the skin effect is pronounced but the radiation and other full-wave effects are still negligible. The model identifies the impedance matrix by enforcing a physically consistent behavior to the resistance and reactance of the package in the low and high frequency limits. The identification is made by using only 5 frequency samples of the impedance matrix, which could be either given by measurements or numerical simulations. In this paper we have used a commercial 3D electromagnetic code (FastHenry) to provide the 5 starting points and the reference values to validate the procedure. Benchmark tests and case-studies are carried out, confirming the accuracy of the model.","PeriodicalId":293987,"journal":{"name":"2010 IEEE 14th Workshop on Signal Propagation on Interconnects","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125650727","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 proposed approach facilitates the inclusion of external uncertainties, like tolerances or process variations, in the circuit analysis. The mechanics of the method amounts to expanding the output variables into a sum of a limited number of orthogonal basis functions and generating an extended matrix for the modified nodal analysis. The advocated method, while providing accurate results, turns out to be more efficient than the classical Monte Carlo technique in determining the circuit response sensitivity to parameters variability.

In our survey, we will show that TSV increases the average wire-length by up to 16 percent that in turn leads to 16 percent elevation in power consumption as well. The 3D TSV effect in wire-length is mapped into a 2D wire-length distribution. The wire-length distribution benefits an accurate continuous stochastic function. There is no need for layout extracted data as to power prediction. The error of prediction is systematic and will also decrease as the circuit size increases.","PeriodicalId":293987,"journal":{"name":"2010 IEEE 14th Workshop on Signal Propagation on Interconnects","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123013460","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}
