4.3.3. IP Core Reset Sequence with the Reconfiguration Controller
If your 100G Interlaken IP core targets an Arria V device or a Stratix V device, you must connect the 100G Interlaken IP core to an Intel® Reconfiguration Controller. At power up, the Reconfiguration Controller configures the transceivers. After power up, upon completion of the transceiver configuration process, the Reconfiguration Controller returns control of the reset to your application. You must wait until the Reconfiguration Controller completes configuration of the transceivers before you assert the reset_n signal.
The Reconfiguration Controller indicates the end of the configuration cycle by deasserting the reconfig_busy signal. After reconfig_busy is deasserted, you can assert reset_n. Intel® recommends that you hold the reset_n signal low for at least the duration of two mm_clk cycles, to ensure the reset sequence proceeds correctly.
You must wait at least 223 mm_clk cycles (or 29 mm_clk cycles in simulation) after the mgmt_clk locks before you deassert the mgmt_rst_reset input signal to the reconfiguration controller.
