Intel Stratix 10 - SDM_IO Pins

CONF_DONE and INIT_DONE are optional signals. You can use these pins for other
functions that the Intel Quartus Prime Pro Edition Device and Pin Options menu
defines.
Debugging Suggestions
Place the CONF_DONE and INIT_DONE pins on the SDM_IO pins that correlate with the
board-level connection. Refer to SDM Pin Mapping and Setting Additional Configuration
Pins for more information.

6.4.4. SDM_IO Pins
Intel Stratix 10 devices include 17 SDM_IO pins that you can configure to implement
specific functions such as CONF_DONE and INIT_DONE. The chosen function must
follow the Intel Stratix 10GX, MX, TX, and SX Device Family Pin Connections
Guidelines. The configuration bitstream controls the pin locations for the SDM_IO pins.
Internal Intel Stratix 10 circuitry pulls SDM_IO0, SDM_IO8 and SDM_IO16 weakly low
through a 25 kΩ resistor. Internal Intel Stratix 10 circuitry pulls all SDM_IO pins
weakly high during power-on.
Debugging Suggestions
Check the Intel Quartus Prime Pro Edition settings and Fitter report to ensure that the
SDM_IO configuration matches your PCB design. The following screen shots show
where to configure these signals and how to confirm the SDM_IO pin settings in the
Fitter report.
