The following sequence of events occur for the reset sequence of the receiver:
1. The SDI MegaCore function resets the Rx transceiver (analog and digital reset are
asserted) after detecting a change in the data rate.
2. The SDI MegaCore function asserts SDI_START_RECONFIG to make a
reconfiguration request to the ALT2GXB_RECONFIG block. The
ALT2GXB_RECONFIG block sets SDI_RECONFIG_DONE to 0, which indicates to the
MegaCore function that the reconfiguration is in progress.
3. When the reconfiguration has been performed, the ALT2GXB_RECONFIG block
sets the SDI_RECONFIG_DONE to logic 1, which indicates to the SDI MegaCore
function to start locking to the incoming data. The analog reset of the SDI
MegaCore function receiver is deasserted.
4. When the CDR PLL locks to the received data (HD/3G mode) or reference clock
(SD mode) successfully, the digital reset of the SDI MegaCore function receiver is
deasserted so that the receiver can continue to process valid data.
5. The SDI MegaCore function sets the SDI_START_RECONFIG line to 0 to indicate that
the request is completed and acknowledged.
Generation of ROM Contents
For Arria GX and Stratix II GX devices, the contents of the ROM are set by .mif . The
Quartus II software outputs the .mif for the configuration settings of the ALT2GXB
instance that is set by the design.

This file generation is not performed by default. You must adjust the Fitter settings.
On the Assignments menu, click Settings . In the Settings dialog box, click Fitter
Settings , and then click More Settings . In the Name list, select Generate GXB
Reconfig MIF and in the Setting list, select On .
