Completing your design includes additional steps to specify analog properties, pin assignments, and
timing constraints.
Making Analog QSF Assignments Using the Assignment Editor
You specify the analog parameters using the Quartus II Assignment Editor, the Pin Planner, or through
the Quartus II Settings File
.(qsf)
.

The Quartus II software provides default values for analog parameters. You can change the defaults using
the Assignment Editor or the Pin Planner. You can also edit your
.qsf
directly or by typing commands in
the Quartus II Tcl Console.
The following example shows how to change the value of the voltages required:
1. On the Assignments menu, select Assignment Editor. The Assignment Editor appears.
2. Complete the following steps for each pin requiring the V
CCR_GXB
and V
CCT_GXB
voltage:
a. Double-click in the Assignment Name column and scroll to the bottom of the available
assignments.
b. Select VCCR_GXB/VCCT_GXB Voltage.
c. In the Value column, select 1_1V from the list.
3. Complete the following steps for each pin requiring the V
CCA_GXB
voltage:
a. Double-click in the Assignment Name column and scroll to the bottom of the available
assignments.
b. Select VCCA_GXB Voltage.
c. In the Value column, select 3_0V from the list.
The Quartus II software adds these instance assignments commands to the
.qsf
file for your project.
