Hierarchical Design Challenge: New Ports Added!

A Buck Converter is implemented as a hierarchical block in the parent schematic.

Initially, the child schematic contained only Vin, Vout, and PWM ports, and the H-Block was already placed and connected.


Later, the design was expanded and two new ports were added to the child schematic: PGOOD and Fault



How would you update the existing H-Block in the parent schematic so the new ports become available?

A. Delete and recreate the H-Block
B. Manually add and rename hierarchical pins
C. Synchronize Up the Hierarchical Block 
D. Synchronize Down the Hierarchical Block
