Channel Power (W)
This shows the total power of the GXB transmitter
channel PMA and GXB receiver channel PMA
blocks for all channels (in watts). This value is
automatically calculated.
CCU Power (W)
This shows the total power of the GXB PLLs and
control circuitry for all channels (in watts). This
value is automatically calculated.
XCVR Power (W)
This shows the sum of the channel power and CCU
power (in watts). This value is automatically
calculated.
PCS/HIP Power (W)
This shows the total power of the GXB transmitter
channel PCS, GXB receiver channel PCS, and PCIe
hard IP blocks for all channels (in watts). This value
is automatically calculated.
User Comments
Enter any comments. This is an optional entry.
Values of some settings in the XCVR worksheet are restricted for one of the following reasons:
• The setting value is restricted due to the selections made for other settings.
• Changing the setting would not have a significant impact on power, given the selected values of other
settings.
For more information about the transceiver architecture of the supported device families, refer to the
“Transceiver Architecture” chapter in the respective device handbook.
HMC Worksheet
The EPE spreadsheet version 11.1 introduces the HMC worksheet. Each row in the HMC worksheet
represents a single instance of the HMC interface. Enter the information for HMC instances in different
rows, even if some of the HMC instances have the same configuration. Specify the following information
for each HMC instance:
• Clock frequency (in MHz)
• DRAM interface width
• Number of command port
• Fabric interface width
The HMC worksheet is only applicable to Arria V and Cyclone V device families with HMC controllers.
