Table 6–9. AFI New Signal Names
This section describes the typical modules that are connected to the UniPHY PHY and
the port name prefixes each module uses. This section describes using a custom
controller and describes the AFI.
The AFI standardizes and simplifies the interface between controller and PHY for all
Altera memory designs, thus allowing you to easily interchange your own controller
code with Altera's high-performance controllers. The AFI PHY includes an
administration block that configures the memory for calibration and performs
necessary accesses to mode registers that configure the memory as required (these
calibration processes are different).
For half-rate designs, the address and command signals in the UniPHY are asserted
for one mem_clk cycle (1T addressing), such that there are two input bits per address
and command pin in half-rate designs. If you require a more conservative 2T
addressing, drive both input bits (of the address and command signal) identically in
half-rate designs.
