15:30 → 15:45 Summary of all simulations of testchip A

• Summary of simulations done with testchip v1
• Vref cap variations
• Oscillations when using USP VS type of load (ohmic, DC)
• Startup: differences seen in simulation wrt to RD53A (oscillations, needed current)
• Behavior with USP deactivated (not disconnected)
• Other effects seen in simulation to be verified with measurements

Speaker: Alvaro Pradas Luengo (Aragon Institute of Technology (ES))

16:00 → 16:15 Discussion for further steps

• Critical items for testchip v2
• Major differences in performance expected in the next version
• First things to test/validate if it arrives before the review
• Improvements in the startup
