One of the most detrimental root causes of I/O signals conducted EMI is the simultaneous switching noise generated by the toggling I/Os (SSO) on the power distribution network of the I/O ring. However, this is not the only noise source that must be considered. In fact, an often overlooked contributor to SSO is the noise generated by the switching digital core that propagates to the I/Os and the noise-sensitive on-chip analog circuitry throughout the common silicon substrate. In this work, we analyze the impact of substrate noise on the I/O signals conducted EMI of an industrial automotive microcontroller, and we compare it against other noise sources. Moreover, we demonstrate the effectiveness of the technological protections against substrate noise in a leading-edge technology.","PeriodicalId":302757,"journal":{"name":"2013 9th International Workshop on Electromagnetic Compatibility of Integrated Circuits (EMC Compo)","volume":"47 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":"123371596","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}

As the major consequence, the system's reliability degrades. In this paper, we present the most recent results involving the reliability analysis of a hardware-based intellectual property (IP) core, namely Real-Time Operating System - Guardian (RTOS-G). This is an on-chip watchdog that monitors the RTOS' activity in order to detect faults that corrupt tasks' execution flow in embedded systems running preemptive RTOS. Experimental results based on the Plasma processor IP core running different test programs that exploit several RTOS resources have been developed. During test execution, the proposed system was aged by means of total ionizing dose (TID) radiation and then, exposed to radiated EMI according to the international standard IEC 62.132-2 (TEM Cell Test Method). The obtained results demonstrate the proposed approach provides higher fault coverage and reduced fault latency when compared to the native (software) fault detection mechanisms embedded in the kernel of the RTOS.","PeriodicalId":302757,"journal":{"name":"2013 9th International Workshop on Electromagnetic Compatibility of Integrated Circuits (EMC Compo)","volume":"21 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":"134355650","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 impacts of in-band spurious tones on wireless performance are explored with hardware-in-the-loop simulation (HILS) of the LTE compliant systems. RF receiver circuits fabricated in a 65 nm CMOS technology are involved in the HILS, for combining circuit-level interactions at the front end and system-level digital signal processing in the back end. Experiments exhibit the sensitivity of LTE communication throughput against substrate coupling noise from a digital noise emulator to the RF receiver circuits on the same chip. The observed response is equivalently confirmed with the input referred RF sinusoidal noise components intentionally added to the input RF signal with LTE modulation. The HILS enables hierarchical diagnosis of a wireless communication system from circuit-level interactions to system-level responses against noise coupling.","PeriodicalId":302757,"journal":{"name":"2013 9th International Workshop on Electromagnetic Compatibility of Integrated Circuits (EMC Compo)","volume":"6 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":"131478500","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}

In the goal to study the electromagnetic immunity of integrated circuits, devices are biased at low current level. Specific interference frequency bands induce changes in the transistor output voltage, even with frequency values out of band of operation of the devices. Analysis of results obtained under CW signal injection highlights the presence of physical phenomena of rectification and ac current crowding. Pulse-modulated sines show that the amplitude of the interference mean power influences the value of the output voltage offset. Parameters of the pulse interference can be changed to modify the transient response of the transistor.","PeriodicalId":302757,"journal":{"name":"2013 9th International Workshop on Electromagnetic Compatibility of Integrated Circuits (EMC Compo)","volume":"15 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":"124548952","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}
