Currently selected device family
Specifies the device family you chose on page 2a.
Match project/default
Turn on this option to ensure that the device selected
matches the device family that is chosen in the previous
page.
Calibrate OCT on power-up
Turn on this option if you want to calibrate OCT on
power-up.
How many OCT blocks should be used?
Specify the number of OCT blocks for your design.
Enable parallel termination
Turn on this option if you want to enable parallel
termination instead of series termination. Observe the
changes in resource usage when this option is enabled.
Create ‘calibration_wait’ input port to prevent
calibration
The
calibration_wait
input port can be used to halt
calibration operation. This option is for advanced users
only. Typical users should not enable this option.
Create ‘clken’ input port
The
clken
input port is used as the clock enable signal.
This option is for advanced users only. Typical users
should not enable this option.
Enable independent calibration/shift
Turn on this option to enable independent
calibration/shift.

Generate netlist
Turn on this option if you want to generate a netlist for
your third-party EDA synthesis tool to estimate the timing
and resource usage of the megafunction. If you turn on
this option, a netlist file (_syn.v) is generated. This file is
a representation of the customized logic used in the
Quartus
®
II software and provides the connectivity of the
architectural elements in the megafunction but may not
represent true functionality.

Summary Page
Specify the types of files to be generated. The Variation
file (<function name>.v) contains wrapper code in the
language you specified on page 2a and is automatically
generated. Choose from the following types of files:
■
AHDL Include file (<function name>.inc)
■
VHDL component declaration file
(<function name>.cmp)
■
Quartus II symbol file (<function name>.bsf)
■
Instantiation template file (<function name>_inst.v)
■
Verilog HDL black box file (<function name>_bb.v)
For more information about the wizard-generated files,
refer to the Quartus II Help or to the
chapter in volume 1 of the Quartus II
Handbook.
