The FC-BGA pattern implemented on the AM62x (AMC) design offers several opportunities for via sharing. Vias are shared across BGA pins. Figure 4-1 and Figure 4-2 show the via sharing opportunities for VDD_CORE and VSS power supplies respectively. Further opportunities for other power domains are illustrated in Figure 4-3. Via sharing across BGA pins provides for easier escape routing and also robust electrical connection by connecting multiple pins.
