Unused SDM Pins
You can specify other functions on unused SDM pins in the Intel Quartus Prime
software.

Note: To avoid false signaling indicating successful configuration, Intel recommends that you
include an external weak pull-down resistor for CONF_DONE and INIT_DONE pins.

Functional Description
CONF_DONE
• SDM_IO5
(9)
• SDM_IO16
SDM_IO16 Allows you to monitor if device configuration is completed.
During power-up, the SDM boot-up, and configuration
stages, the pin is pulled low. Upon successful configuration,
the pin is driven high by the Intel Stratix 10 device.
INIT_DONE
• SDM_IO0
• SDM_IO16
• SDM_IO5
(10)
SDM_IO0 Allows you to monitor if device initialization is completed.
During power-up, the SDM boot-up, configuration, and
initialization stages, the pin is pulled low. Upon successful
initialization, the pin is driven high by the Intel Stratix 10
device.
SDM pins are also available for the SmartVID power management feature for -V
devices. You must also set the correct Power Management Bus (PMBus) settings when
using the SmartVID feature. Refer to the Intel Stratix 10 Power Management User
Guide for more information about the pin assignments and PMBus setting.

2.4.4. Setting Additional Configuration Pins
You enable and assign the SDM pins for CONF_DONE and INIT_DONE functions in the
Intel Quartus Prime software.
Complete the following steps to assign additional configuration pins:
1. On the Assignments menu, click Device.
2. In the Device and Pin Options dialog box, select the Configuration category
and click Configuration Pins Options.
3. In the Configuration Pin window, enable and assign the configuration pin that
you want to enable.
