Manual Timings
The manual timing settings do not need to be changed under normal circumstances.
For more information on the manual timing settings, refer to “Manual Timing
Settings” on page A–1 .
MegaCore Verification
MegaCore verification involves simulation testing and hardware testing.
Simulation Testing
Altera has carried out extensive random, directed tests with functional test coverage
using industry-standard Denali models to ensure the functionality of the DDR and
DDR2 SDRAM controller. In addition, Altera has carried out a wide variety of gate-
level tests of the DDR and DDR2 SDRAM controllers to verify the post-compilation
functionality of the controllers.
Hardware Testing
Table 3–25 shows the Altera development boards on which Altera hardware tested
the DDR and DDR2 SDRAM controllers.
