Advanced Design and SIL Verification (EC54) 

man-working-at-desk-with-computer-and-paperwork
Advanced Design and Safety Integrity Level (SIL) Verification (EC54) focuses on detailed design issues and hands-on system analysis and modeling examples. Students will learn to analyze a system’s technology and configuration to see if it meets the required Safety Integrity Level (SIL), and to decide if existing systems are safe or if they need to be upgraded. EC54 will better enable students to perform system design and analysis and recognize whether proposed systems meet the performance requirements. This course will also show students how to determine the optimum manual test interval for any system to prevent over- or under-testing systems.
