Abstract

Most chip designers outsource the manufacturing of their integrated circuits (ICs) to external foundries due to the exorbitant cost and complexity of the process. This involvement of untrustworthy, external entities opens the door to major security threats, such as reverse engineering (RE). RE can reveal the physical structure and functionality of intellectual property (IP) and ICs, leading to IP theft, counterfeiting, and other misuses. The concept of the threshold voltage-defined (TVD) logic family is a potential mechanism to obfuscate and protect the design and prevent RE. However, it addresses post-fabrication RE issues, and it has been shown that dopant profiling techniques can be used to determine the threshold voltage of the transistor and break the obfuscation. In this work, we propose a novel TVD modulation with ion-sensitive field-effect transistors (ISFETs) to protect the IC from RE and IP piracy. Compared to the conventional TVD logic family, ISFET-TVD allows post-manufacture programming. The ISFET-TVD logic gate can be reconfigured after fabrication, maintaining an exact schematic architecture with an identical layout for all types of logic gates, and thus overcoming the shortcomings of the classic TVD. The threshold voltage of the ISFETs can be adjusted after fabrication by changing the ion concentration of the material in contact with the ion-sensitive gate of the transistor, depending on the Boolean functionality. The ISFET is CMOS compatible, and therefore implemented on 45 nm CMOS technology for demonstration.

Abstract

Background: Maternity hospitals everywhere are seeing a rise in the trend of Caesarean deliveries, the indications for which are varied and could be maternal, fetal or fetomaternal. The objective of the study was to find out the factors associated with the indications for emergency Caesarean sections. Methodology: Retrospective case-control study conducted in Kasturba Medical College Hospital, Attavar and Govt. Lady Goschen Hospital, Mangalore, among women who underwent caesarean sections as cases, and equal number of age matched women who underwent normal deliveries as controls, a total sample size of 70, during the study period 12th April 2016 to 22nd April 2016. A questionnaire was used to collect details including the social- demographic details, antenatal history, and indications for caesarean section. Results: The study showed that 37.1% of women who underwent emergency LSCS were ≤25 years, 34.3% were between 26-30 years, and 28.6% were ≥31 years. Regarding occupation 88.6%of our cases did non strenuous work whereas 11.4% did strenuous work(manual labourer). 20% of our cases were vegetarians and 80% consumed a mixed diet. 71.4% cases were primigravids and 28.6% were non primis. Regarding antenatal visits 85.7% who underwent emergency LSCS made regular antenatal visits and 14.3% were irregular. Conclusion: Among the women that underwent full term vaginal delivery (FTVD), it was observed that they did moderate physical work. Older women (above 30 years) were observed to have undergone emergency LSCS rather than vaginal deliveries. It was seen that most of the women who had a full-term vaginal delivery consumed a mixed diet. Those who underwent emergency LSCS were observed to be mostly primigravida and primipara.

Abstract

Design of printed circuit board (PCB) stack-up requires the consideration of characteristic impedance, insertion loss and crosstalk. As there are many parameters in a PCB stack-up design, the optimization of these parameters needs to be efficient and accurate. A less optimal stack-up would lead to expensive PCB material choices in high speed designs. In this paper, an efficient global optimization method using parallel and intelligent Bayesian optimization is proposed for the stripline design., Comment: 3 Pages
