Using the PowerPlay Early Power Estimator
Figure 3–22 shows the PowerPlay Early Power Estimator spreadsheet
and the estimated power consumed by clocks for this design.

Transceiver (XCVR)
Stratix II GX devices feature dedicated embedded circuitry on the right
side of the device that contain up to 20 high-speed 6.375 Gbps serial
transceiver channels. Stratix II GX devices have dedicated transmitters
and receivers that contain serializer and deserializer blocks, respectively.
This section, therefore, is only applicable for designs targeting Stratix II
GX devices.

The power calculated in this section applies to the transceiver blocks,
including the channels used and all circuitry used in the Clock Control
Unit (CCU). The transceivers are implemented using the ALT2GXB
megafunction. The I/O buffer power and the PLL power for the
transceivers are included in this section. Transmitters and receivers
assume 100
Ω termination.
