Parameter
Type
Description
outclock_alignment
String
Specifies the alignment of
tx_outclock
with respect
to the VCO of a fast PLL. The clock phase alignment
for the
outclock_alignment
parameter is data
leading.
This parameter is only used by the RTL simulation
model and has no affect on how the Fitter sets the
PLL parameters.
Values are:
•
EDGE_ALIGNED: 0°
•
45_DEGREES: 45°
•
90_DEGREES: 90°
•
135_DEGREES: 135°
•
CENTER_ALIGNED:180°
•
225_DEGREES: 225°
•
270_DEGREES: 270°
•
315_DEGREES: 315°
If omitted, the default value is
EDGE_ALIGNED
.
Available for all devices excluding the MAX series.
outclock_divide_by
Integer
Specifies the period of the
tx_outclock
port as
[INCLOCK_PERIOD * OUTCLOCK_DIVIDE_BY]
and the
frequency of the
tx_outclock
port as
[INCLOCK_
PERIOD/OUTCLOCK_DIVIDE_BY]
. The default value for
this parameter is the value of the
deserialization_
factor
parameter.
Only available for Arria GX, Arria II GX, Arria II GZ,
Arria V, Arria V GZ, Cyclone, Cyclone II, Cyclone
III, Cyclone IV, HardCopy II, HardCopy III,
HardCopy IV, Stratix, Stratix GX, Stratix II, Stratix II
GX, Stratix III, Stratix IV, and Stratix V devices.
