■ 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 “Streamer Based Reconfiguration” on page 10–28. 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” on page 10–29.
Table 10–1 shows the features that you can reconfigure or control using register-based
and MIF-based access modes.
Device Family Support
IP cores provide either final or preliminary support for target Altera device families.
These terms have the following definitions:
■ Final support—Verified with final timing models for this device.
■ Preliminary support—Verified with preliminary timing models for this device.
Table 10–2 lists the level of support offered by the Transceiver Reconfiguration
Controller for Altera device families.
