This paper studies especially the influence of damping and leakage on the mid-frequency power noise caused by switching activity variations of logic circuits. The noise is determined by simulations and calculated by a closed form expression which is derived for a simplified 2D circuit representation of the chip and package power delivery network. Both approaches agree within 16%. The voltage dependency of the leakage resistance is found to be essential for the power noise when the noise is determined by the resonance between on-die capacitors and the next stage of decoupling capacitors. It is shown that damping and leakage reduce significantly the influence of the on-die decoupling capacitance and package capacitor inductance on the mid-frequency power noise.","PeriodicalId":119776,"journal":{"name":"Proceedings. 8th IEEE Workshop on Signal Propagation on Interconnects","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2004-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134631424","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 combines an iterative solution of the pertinent integral equations with the non-uniform grid (NG) algorithm for fast evaluation of potentials due to given source distributions. The NG approach is based on the observation that locally the potential produced by a finite size source can be interpolated from its samples at a small number of points of a non uniform spherical grid. This observation leads to a multilevel algorithm comprising interpolation and aggregation of potentials. The resulting hierarchical algorithm attains an O(N) asymptotic complexity.","PeriodicalId":119776,"journal":{"name":"Proceedings. 8th IEEE Workshop on Signal Propagation on Interconnects","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2004-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114517015","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}

Such a model, while retaining the same simplicity of a transmission line model, describes accurately the case where the signal characteristic wavelength is comparable to the interconnect transverse dimension. The model has been obtained from an integral formulation of the propagation problem by using electromagnetic potentials with Lorenz gauge, with reference to a pair of cylindrical wires in homogeneous dielectric. Here the model is extended to interconnects with arbitrary cross-sections, embedded in a non-homogeneous dielectric. The main difference is in the reformulation of the problem by adding new unknowns (the polarization charges and displacement currents of the dielectrics), so that the potential may still be expressed through the Green function of the free space.","PeriodicalId":119776,"journal":{"name":"Proceedings. 8th IEEE Workshop on Signal Propagation on Interconnects","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2004-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132223414","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}

Part of this discussion is the on-chip /spl Delta/I-noise. Various simulation methodologies, e.g. RAPiD, are known for simulation. Characteristic for these simulations is the very time consuming task of collecting and processing the complex input data, in order to optimise the required effort a sensitivity analysis for high-frequency on-chip /spl Delta/I-noise simulation has been carried out. This paper describes the results of this sensitivity analysis. A generic description of the on-chip /spl Delta/I-noise simulation methodology is shown. In particular the required input data is described. The sensitivity analysis quantifies the impact of each simulation parameter on the simulation results. The nominal value of each input parameter has been varied in a range from 0.5x to 2.0x compared to a nominal case. The maximum HF /spl Delta/I-noise is measured and plotted versus the respective input parameter deviation. The input parameters are categorized in high, medium and low impact parameters. This analysis results in guidelines which design parameters most efficiently reduce HF-noise and/or which input parameter need to be accurate in order to obtain accurate simulation results.","PeriodicalId":119776,"journal":{"name":"Proceedings. 8th IEEE Workshop on Signal Propagation on Interconnects","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2004-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114194043","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}
