The Altera QDR II and QDR II+ SRAM controllers with UniPHY provide simplified
interfaces to industry-standard QDR II and QDR II+ SRAM.
The QDR II and QDR II+ SRAM controllers with UniPHY offer full-rate or half-rate
QDR II and QDR II+ SRAM interfaces. The UniPHY IP is an interface between a
memory controller and memory devices and performs read and write operations to
the memory. The UniPHY IP creates the datapath between the memory device and the
memory controller and user logic in various Altera devices.
The Quartus II software generates an example top-level project, consisting of an
example driver, and your QDR II or QDR II+ SRAM controller custom variation. The
controller instantiates an instance of the UniPHY.
The example top-level project is a fully-functional design that you can simulate,
synthesize, and use in hardware. The example driver is a self-test module that issues
read and write commands to the controller and checks the read data to produce the
pass or fail and test-complete signals.
For device families not supported by the UniPHY IP, use the Altera legacy integrated
static datapath and controller MegaCore functions.
You can, alternatively, create your own memory interface datapath using the ALTDLL
and ALTDQ_DQS megafunctions, available in the Quartus II software, but you then
must consider all of the aspects of the design including timing analysis and design
constraints.
The UniPHY IP offers the Altera PHY interface (AFI). The AFI results in a simple
connection between the PHY and controller.
