QSF Assignment
To enable the series/parallel termination ports,
include these assignments which will specify the
series and parallel termination values for the pins.
Make sure to connect the seriesterminationcontrol
and parallelterminationcontrol ports from the
Altera OCT megafunction to the Altera GPIO
megafunction.
Example
set_instance_assignment -name
INPUT_TERMINATION "PARALLEL
<VALUE> OHM WITH CALIBRATION"
-to <pin>
set_instance_assignment -name
OUTPUT_TERMINATION "SERIES
<VALUE> OHM WITH CALIBRATION"
-to <pin>
INPUT_TERMINATION
OUTPUT_TERMINATION
Directs the Fitter to make the proper connection
from the desired OCT block to the specified pins.
Example
set_instance_assignment -name
TERMINATION_CONTROL_BLOCK
<desired OCT BLK> -to <pin
name>
TERMINATION_CONTROL_BLOCK
This assignment is supported in Arria 10 devices
only. This assignment creates an Altera OCT
megafunction without modifying the RTL.
The Fitter searches for the rzq pin name in the
netlist. If the pin does not exist, the Fitter creates
the pin name along with the Altera OCT
megafunction and its corresponding connections.
This allows you to create a group of pins to be
calibrated by an existing or non-existing OCT and
the Fitter ensures the legality of the design.
Example
set_instance_assignment -name
RZQ_GROUP <rzq pin name> -to
<pin name>
RZQ_GROUP
