Here are some very common causes of configuration failures:
•
Check
Intel Quartus Prime Software and the clock source on your board.
• Ensure a free running reference clock is present for designs using transceivers,
PCIe, or HBM2.
• For designs using the HPS and the external memory interface (EMIF), ensure that
the EMIF clock is present.
• For designs using SmartVID (-V devices), ensure that this feature is set-up and
operating correctly. Ensure that the voltage regulator supports SmartVID.
Here are some debugging suggestions that apply to any configuration mode:
•
To rule out issues with
Intel Quartus Prime.
• Try configuring the Intel Stratix 10 device with a simple design that does not
contain any IP. If configuration via a non-JTAG scheme fails with a simple design,
try JTAG configuration with the
The following topics describe the expected behavior of configuration pins. In addition,
these topics provide some suggestions to assist in debugging configuration failures.
Refer to the separate sections on each configuration scheme for debugging
suggestions that pertain to a specific configuration scheme.
