7–16 Chapter 7: Interlaken PHY IP Core
Dynamic Transceiver Reconfiguration Interface
Altera Transceiver PHY IP Core November 2012 Altera Corporation
User Guide
Dynamic Transceiver Reconfiguration Interface
Table 711 describes the signals in the reconfiguration interface. This interface uses the
Avalon-MM PHY Management interface clock.
Transceiver dynamic reconfiguration requires that you assign the starting channel
number.
TimeQuest Timing Constraints
You must add the following TimeQuest constraint to your Synopsys Design
Constraints File (.sdc) timing constraint file:
derive_pll_clocks -create_base_clocks
Simulation Files and Example Testbench
Refer to “Running a Simulation Testbench” for a description of the directories and
files that the Quartus II software creates automatically when you generate your
Interlaken PHY IP Core.
f Refer to the Altera wiki for an example testbench that you can use as a starting point
in creating your own verification environment.
Table 7–11. Reconfiguration Interface
Signal Name Direction Description
reconfig_to_xcvr [(<n>70)-1:0]
Input
Reconfiguration signals from the Transceiver Reconfiguration
Controller. <n> grows linearly with the number of
reconfiguration interfaces. <n> initially includes the total
number transceiver channels and TX PLLs before
optimization/merging.
reconfig_from_xcvr [(<n>46)-1:0]
Output
Reconfiguration signals to the Transceiver Reconfiguration
Controller. <n> grows linearly with the number of
reconfiguration interfaces.
<n>
initially includes the total
number transceiver channels before optimization/merging.
