Here a new generalized approach to develop accurate component-based models of different system-level EMC test setups is proposed on the example of a BCI test setup. An equivalent circuit modelling of the components in LF range is combined with measurement-based macromodelling in HF range. The developed models show high accuracy up to 1 GHz. The issues of floating PCB configurations and incorporation of low frequency behaviour could be solved. Both frequency and time-domain simulations are possible. Arbitrary system configurations can be assembled quickly using the proposed component models. Any kind of system simulation like parametric variation and worst-case analysis can be performed with high accuracy.","PeriodicalId":302757,"journal":{"name":"2013 9th International Workshop on Electromagnetic Compatibility of Integrated Circuits (EMC Compo)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123934057","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 logic gates are based on buffer design using dynamic threshold voltage MOS (DTMOS) for low power operation (VDD=0.4V).

In recent years, security threats based on EM analysis attacks on cryptographic devices are attracting considerable attention due to their relative simplicity in practice. Some of the most cost-effective countermeasures against such attacks can be implemented at the PCB level. In order to implement such countermeasures effectively, critical parts (i.e., information sources and information propagation paths) on the board should be identified in advance. The key idea behind this identification is to calculate a correlation between measured EM traces and EM intensity values estimated from correct information (secret key) in the time domain. Transient analysis can reveal information propagation paths even if the EM signal carrying information is weak in comparison with noise generated from other components. Through an experiment, we confirm that EM radiation associated with information leakage can be traced even in situations where the information signal is obscured by background noise.","PeriodicalId":302757,"journal":{"name":"2013 9th International Workshop on Electromagnetic Compatibility of Integrated Circuits (EMC Compo)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134281408","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 equivalent circuit model was Linear Equivalent Circuit and Current Source (LECCS) model representing dynamic switching current inside the FPGA with an equivalent current source. The current source was supposed to depend on input data for the FPGA on which a cryptographic circuit was implemented. Model identification was based on the procedure of LECCS model identification from on-board measurements and the current source was identified for all values of input data used in this work. The identified current source was investigated in accordance with the operation process of the cryptographic circuit and found an excellent correlation to the operation process. The identified LECCS model was combined with an equivalent circuit of the power distribution network for the FPGA core circuit to simulate power voltage variations for the 1,000 input texts. The simulated variation waveforms were compared to the corresponding measured ones to evaluate the LECCS model. Results indicated that the simulated and measured power variations matched excellently for all input data with high cross-correlation coefficients from 0.7 to 0.9. LECCS model is, therefore, able to predict the data-dependent power voltage variation by combining a PDN equivalent circuit.","PeriodicalId":302757,"journal":{"name":"2013 9th International Workshop on Electromagnetic Compatibility of Integrated Circuits (EMC Compo)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130754691","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}

So chip level counter-measure is even more important to reduce EMI as an excitation source of noise. In this paper, power supply noise was evaluated by fabricating two circuit blocks in a test chip. One was with on-chip capacitance consisted of intentional MOS (metal-oxide semiconductor) capacitors and MIM (metal-insulator-metal) capacitors, and the other was without any intentional capacitors. Reduction effect of power supply noise and the impedance of PDN (power distribution network) at each circuit block were evaluated based on chip-package-board co-design.

Especially, anti-resonance peaks in power distribution network (PDN) due to the chip-package interaction induce the unwanted power supply fluctuation, and result in large electromagnetic radiation. In this paper, power supply noises and total impedances of power distribution network (PDN) for the variable structure of on-die capacitances have been examined. In addition, power supply noise and total PDN impedance have been examined by changing the number of power supply terminals. As a result, it has been proved that anti-resonance peaks could be controlled by on-die capacitance and the number of power supply terminals. Simulated anti-resonance peak frequencies were well correlated with the peak frequency spectra of measured power supply noise.","PeriodicalId":302757,"journal":{"name":"2013 9th International Workshop on Electromagnetic Compatibility of Integrated Circuits (EMC Compo)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125315221","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}
