Parameter
Description
General Settings
Extra output-only pins
This option is commonly used as datamask pins
in the ALTDQ_DQS2 IP core. In the Altera
PHYLite for Parallel Interfaces IP core, you may
implement this as part of the data group.
Note: An I/O bank comprises of 48 I/O
pins (up to 48 data I/Os as well as the
strobe capture logic).
Use DLL Offset Control
You cannot access the DLL because the DLL is
an internal block in Arria 10 devices.
Note: This feature is only for testing
purposes in the ALTDQ_DQS2 IP
core.
Enable hard FIFOs
In Arria 10 devices, the FIFOs are built-in and
is always enabled. But you can decide on the
full/half/quarter rate conversion to achieve the
equivalent data width and rate with the
ALTDQ_DQS2 IP core.
Enable dual write clocks
Enabled the use of separate output clocks for
data and strobe in the ALTDQ_DQS2 IP core.
Equivalent implementation is available in the
Altera PHYLite for Parallel Interfaces IP core.
You can control the phase shift with the Output
Strobe Phase parameter in the Altera PHYLite
for Parallel Interfaces IP core.
Use capture clock to clock the read
side of the Hard FIFO (For Arria V
and Cyclone V devices only)
This feature is not supported in the Altera
PHYLite for Parallel Interfaces IP core. This
parameter is only available for Arria V and
Cyclone V devices.
Output Path
Use output phase alignment blocks
Arria 10 devices have different architecture.
