Abstract Background We report the implementation of a large-scale simulation-based cardiovascular diagnostics course for undergraduate medical students. Methods A simulation-based course was integrated into the curriculum of second-year medical students (> 400 students/year). The first session aimed at teaching cardiac auscultation skills on mannequins and the second at teaching blood pressure measurement, peripheral arterial examination, and the clinical examination of heart failure in a technical skill-based manner and in a scenario. Results A total of 414 (99.8%) and 402 (98.5%) students, as well as 102 and 104 educators, participated during the 2016–2017 and 2017–2018 academic years across both types of sessions. The number of positive appreciations by students was high and improved from the first to the second year (session 1: 77% vs. 98%, session 2: 89% vs. 98%; p < 0.0001). Similar results were observed for educators (session 1: 84% vs. 98%, p = 0.007; session 2: 82% vs. 98%, p = 0.01). Feedbacks by students were positive regarding the usefulness of the course, fulfillment of pedagogical objectives, quality of the teaching method, time management, and educator-student interactivity. In contrast, 95% of students criticized the quality of the mannequins during the first year leading to the replacement of the simulation material the following year. Students most appreciated the auscultation workshop (25%), the practical aspect of the course (22%), and the availability of educators (21%). Conclusions Despite the need to commit significant human and material resources, the implementation of this large-scale program involving > 400 students/year was feasible, and students and educators reacted favorably.

Soft errors have always been a concern in the design of digital circuits. As technology down-scales toward Nanometer sizes, emergence of aging effects, process variations, and Multiple Event Transients (METs) has made the soft error rate (SER) estimation of digital circuits very challenging. This paper intends to characterize the challenges by investigating the cross effects of theses issues in overall SER of a circuit. To this regard, we employ a simulation-based SER estimation approach in which the aging effect, process variations and METs are jointly considered in our fault injection process. In our simulation-based SER estimation approach, a statistical gate delay model is used. The fault injection results into ISCAS85 circuit benchmark reveal that the SER estimation without taking into account the aging effects, the process variations, and METs is significantly inaccurate.
