Chapter 2: HardCopy IV GX Dynamic Reconfiguration
Combining Transceiver Channels with Dynamic Reconfiguration Enabled
■ TX Data Rate Switch using Local Divider-write operation with unsupported
value option:
■ The rate_switch_ctrl[1:0] input port is set to 11
■ The reconfig_mode_sel[2:0] input port is set to 4 (if other
reconfiguration mode options are selected in the Reconfiguration settings
screen)
■ The write_all is asserted
■ TX Data Rate Switch using Local Divider-write operation without input port
option:
■ The rate_switch_ctrl[1:0] input port is not used
■ The reconfig_mode_sel[2:0] port is set to 4 (if other reconfiguration
mode options are selected in the Reconfiguration settings screen)
■ The write_all is asserted
■ TX Data Rate Switch using Local Divider- read operation without output port
option:
■ The rate_switch_out[1:0] output port is not used
■ The reconfig_mode_sel[2:0] port is set to 4 (if other reconfiguration
mode options are selected in the Reconfiguration settings screen)
■ The read is asserted
■ Channel and/or TX PLL reconfiguration-read operation option:
■ The reconfig_mode_sel[2:0] input port is set to 1, 4, 5, or 6
■ The read signal is asserted
Combining Transceiver Channels with Dynamic Reconfiguration
Enabled
Packing the transceiver channels into the same physical transceiver block is called
“combining”. You can combine the transceiver channels in a design into the same
physical transceiver block by assigning the tx_dataout and rx_datain pins of the
channels to the same transceiver block.
The Quartus II software also allows you to combine multiple channels into the same
physical transceiver block based on the same requirements described in the following
sections.
