In the Cyclone III F780 Development Board Schematic, are the points V1,V2,V3,V4,V5 in the POWER2 sheet the same points as V1,V2,V3,V4,V5 in the DDR2 SDRAM POWER & TERM sheet?

Description

In the Cyclone® III F780 Development Board Schematic, the points V1,V2,V3,V4,V5 in the POWER 2 sheet and points V1,V2,V3,V4,V5 in the DDR2 SDRAM POWER & TERM sheet are NOT the same electrical points.

V1,V2,V3,V4,V5 in the POWER 2 sheet are connected to J13 on the User IO & Connector sheet. For V1,V2,V3,V4,V5 in the DDR2 SDRAM POWER & TERM sheet, you can trace the net name of the point in the schematic to see where it is connected.

For example,
DDR2BOT_CKE -> V1
DDR2BOT_WEn -> V2
DDR2BOT_RASn -> V3
DDR2BOT_ODT -> V4
DDR2BOT_BA2 -> V5

You can verify this in the development board layout file using PCB software tools.
