• The exam is a report to be sent back to E. Sicard & A. Boyer 3 weeks max after the end of the session. It consists in a 3-5 pages report (in English) with 3-10 figures either about:

• the application of the course in your engineering work (engineers, PhD students) or
• the simulation using IC-EMC of an IC case study, inspired from what was conducted during the week, either emission or immunity, with your own comments.

• The evaluation is performed as follows:

• 1) Presentation : quality of writing, clarity of the intro, precise descriptions, conclusion, and clear figures.
• 2) Background : justification of the work, choice of the case study, outlines
• 3) Originality of work : novelty, difficulty of implementation, stages of design, simulations described
• 4) Summary, Prospective : synthesis of the work; limits; future work; problems; personal opinion
• 5) References, links : references to sources (manuals, books, papers, websites)

• A transcript of records in ECTS format from INSA, University of Toulouse, will be delivered (2 credits)
