May 2008 PowerPlay Early Power Estimator For Arria GX FPGAs
Using the PowerPlay Early Power Estimator
Each row in the XCVR section represents a separate transceiver domain.
For each transceiver domain used, you need to enter the number of
channels and the mode of the transceiver.
Table 3–11 describes the values
that need to be entered in the XCVR section of the PowerPlay Early
Power Estimator.
Voltage (V) The voltage applied to the specified power rail in Volts (V). Select V
CCH
= 1.2 V for PCI
Express (PIPE) mode and V
CCH
= 1.5 V for Serial RapidIO mode.
Current (A) The current drawn from the specified power rail in Amps (A).
This includes power drawn by transceivers in user modes and unused transceivers in
power-down mode.

Column Heading Description
Table 3–11. XCVR Section Information (Part 1 of 2)
Column Heading Description
Module Enter a name for the module in this column. This is an optional value.
# of Channels Enter the number of channels used in this transceiver domain. These
channels are grouped together in one transceiver blocks or two adjacent
transceiver blocks and clocked by a common PLL. The number of
channels allowed in each domain depends on selected protocol.
Mode Enter the communication protocol or standard these transceivers
implement. Options include PCI Express (PIPE), Serial RapidIO, GIGE,
Basic 3G, XAUI, CPRI, SDI 3G and SDI HD.
Operation Mode Enter the operation mode implemented by the transceiver block. Options
include:
● Receiver and Transmitter
● Receiver only
● Transmitter only
Data Rate (Mbps) Enter the data rate the transceivers will operate at (in Mbps).
Parallel Data Width Enter the width of the parallel data bus going into each GXB Transmitter
channel PCS and coming out of each GXB Receiver channel PCS.
Byte Serializer Used Enter whether or not the byte serializer/deserializer is used. If the byte
serializer is used, the transceiver is in double-width mode. If it is not used,
the transceiver is in single-width mode.
Rate Match FIFO Used Enter whether or not the rate matching FIFO is used.
8B10B Encoder Used Enter whether or not the 8B/10B encoder/decoder is used.
Pre-Emphasis Setting Pre-Tap Enter the pre-emphasis pre-tap setting used by the transmitter.
Pre-Emphasis Setting First
Post-Tap Enter the pre-emphasis first post-tap setting used by the transmitter.
