Set Implementation Details to "Pin grouping updated from STM32F407VGT6 LQFP-100 pinout. Each of the 100 terminals has one Section and one Pin Group: Power/V..."
Updated all 100 STM32F407VGT6 terminals with a single functional Section, Pin Group, Pin Type, and sub-symbol grouping based on the LQFP-100 pinout: Power/Ground, Analog, Clock, Control, Debug, USB Communication, and GPIO-by-port. Verified the schematic still contains exactly 100 terminals and documented the grouping in STM32F407VGT6 Pin Grouping Summary.
