5.11. Dynamic Reconfiguration Controller Interface Signals

Note: The DR Controller interface signals are not available in the 1G/2.5G/5G/10G Multirate Ethernet PHY IP interfaces. They are the new signals added by the GTS dynamic reconfiguration controller IP to the top level RTL module after the dynamic reconfiguration flow.
Table 28.  DR Controller Interface Signals
Signal Name Direction Width Clock Description PHY Configurations
DR-SRC Interface
i_src_ch_pause_request In 1 csr_clk Request pause signal from GTS Dynamic Reconfiguration Controller IP to reset.  
o_src_ch_pause_grant Out 1 csr_clk Indicates that the reset service pause is acknowledged.  
DR Profile Select
one_hot_sel[Profiles-1:0] In 1: 1G/2.5G csr_clk Connects to o_one_hot_sel on the GTS Dynamic Reconfiguration Controller IP.
Note: This signal can be used for mapping to xcvr_mode interface. When one_hot_sel[1:0]= 2'b10, then xcvr_mode[1:0] = 2'b00. All other values would be xcvr_mode[1:0] = 2'b01.
 
DR Controller Avalon® Memory-Mapped Interface
i_dr_lavmm_clk In 1 32-bit data Avalon® memory-mapped interface reconfiguration interface with 21-bit address. This Avalon® memory-mapped interface needs to be connected to the GTS Dynamic Reconfiguration Controller IP. Not available for the 1G/2.5G/5G/10G Multirate Ethernet PHY IP but added to the mr_top module after the dynamic reconfiguration flow.
i_dr_lavmm_addr In 21
i_dr_lavmm_be In 4
i_dr_lavmm_read In 1
i_dr_lavmm_wdata In 32
i_dr_lavmm_write In 1
o_dr_lavmm_rdata Out 32
o_dr_lavmm_rdata_valid Out 1
o_dr_lavmm_waitreq Out 1
i_dr_lavmm_rstn In 1
Refer to the Dynamic Reconfiguration Flow for the 1G/2.5G/5G/10G Multirate Ethernet PHY interface signals name change after the dynamic reconfiguration.
