User Guide
In addition to customization of the transceiver through the parameter editor (in
variations that target a device for which the transceivers are configured with the
ALTGX megafunction, and not with the Transceiver PHY IP core), you can use the
transceiver reconfiguration block to dynamically modify the parameter interface. The
dynamic reconfiguration block lets you reconfigure the following PMA settings:
■ Pre-emphasis
■ Equalization
■ Offset cancellation
■ V
OD
on a per channel basis
The dynamic reconfiguration block is required for many device families, including
Arria V, Cyclone V, and Stratix V devices. Refer to
Chapter 2, Getting Started .
reconfig_writedata_ch2[31:0] Input
Arria 10 dynamic reconfiguration slave write data bus for the
transceiver channel configured for RapidIO lane 2. This signal is
available only in 4x variations.
reconfig_readdata_ch2[31:0] Output
Arria 10 dynamic reconfiguration slave read data bus for the
transceiver channel configured for RapidIO lane 2. This signal is
available only in 4x variations.
reconfig_clk_ch3 Input
Arria 10 dynamic reconfiguration interface clock for the transceiver
channel configured for RapidIO lane 3. This signal is available only in
4x variations.
reconfig_reset_ch3 Input
Arria 10 dynamic reconfiguration interface reset for the transceiver
channel configured for RapidIO lane 3. This signal is available only in
4x variations.
reconfig_waitrequest_ch3 Output
Arria 10 dynamic reconfiguration slave wait request for the
transceiver channel configured for RapidIO lane 3. The RapidIO IP
core uses this signal to stall the requestor on the interconnect.
This signal is available only in 4x variations.
reconfig_read_ch3 Input
Arria 10 dynamic reconfiguration slave read request for the
transceiver channel configured for RapidIO lane 3. This signal is
available only in 4x variations.
reconfig_write_ch3 Input
Arria 10 dynamic reconfiguration slave write request for the
transceiver channel configured for RapidIO lane 3. This signal is
available only in 4x variations.
reconfig_address_ch3[9:0] Input
Arria 10 dynamic reconfiguration slave address bus for the
transceiver channel configured for RapidIO lane 3. The address is a
word address, not a byte address.
This signal is available only in 4x variations.
reconfig_writedata_ch3[31:0] Input
Arria 10 dynamic reconfiguration slave write data bus for the
transceiver channel configured for RapidIO lane 3. This signal is
available only in 4x variations.
reconfig_readdata_ch3[31:0] Output
Arria 10 dynamic reconfiguration slave read data bus for the
transceiver channel configured for RapidIO lane 3. This signal is
available only in 4x variations.
