You can also enter these commands at the Quartus II Tcl Console. For example, the following command
sets the XCVR_VCCR_VCCT_VOLTAGE to 1.0 V for the pin specified:
set_instance_assignment -name XCVR_VCCR_VCCT_VOLTAGE 1_0V to “pin”

Making Pin Assignments
Before running Quartus II compilation, use the Pin Planner to assign I/O standards to the pins of the
device. Complete the following steps to bring up the Pin Planner and assign the 1.5-V pseudo-current
mode logic (PCML) I/O standard to the serial data input and output pins:
1. On the Quartus II Assignments menu, select Pin Planner. The Pin Planner appears.
2. In the Node Name column, locate the PCIe serial data pins.
3. In the I/O Standard column, double-click the right-hand corner of the box to bring up a list of
available I/O standards.
4. Select 1.5 V PCML I/O standard.
Note:
The IP core automatically assigns other required PMA analog settings, including 100 ohm internal
termination.
Recommended Reset Sequence to Avoid Link Training Issues
1. Wait until the FPGA is configured as indicated by the assertion of CONFIG_DONE from the FPGA block
controller.
2. Deassert the mgmt_rst_reset input to the Transceiver Reconfiguration Controller IP Core.
3. Wait for tx_cal_busy and rx_cal_busy SERDES outputs to be deasserted.
4. Deassert pin_perstn to take the Hard IP for PCIe out of reset. For plug-in cards, the minimum
assertion time for pin_perstn is 100 ms. Embedded systems do not have a minimum assertion time
for pin_perstn.
5. Wait for thereset_status output to be deasserted
6. Deassert the reset output to the Application Layer.
