User Guide
1 For more information about Avalon-MM interfaces including timing
diagrams, refer to the Avalon Interface Specifications.
Streamer Based —This access mode allows you to either stream a MIF that
contains the reconfiguration data or perform direct writes to perform
reconfiguration. The streaming mode uses a memory initialization file (.mif) to
stream an update to the transceiver PHY IP core. The .mif file can contain changes
for many settings. For example, a single .mif file might contain changes to the PCS
datapath settings, clock settings, and PLL parameters. You specify the .mif using
write commands on the Avalon-MM PHY management interface. After the
streaming operation is specified, the update proceeds in a single step. For more
information, refer to Changing Transceiver Settings Using Streamer-Based
Reconfiguration. In the direct write mode, you perform Avalon-MM reads and
writes to initiate a reconfiguration of the PHY IP. For more information, refer to
Direct Write Reconfiguration.
Table 162 shows the features that you can reconfigure or control using register-based
and MIF-based access modes for Stratix V devices. Arria V and Cyclone V devices
support register-based mode.
Device Family Support
