Why does nSTATUS assert and stay low after a configuration failure in Intel® Stratix® 10 devices, when using configuration files generated in Intel Quartus® Prime Pro version 18.0?

Description

When configuring Intel® Stratix® 10 devices with a configuration file generated in Intel Quartus® Prime Pro software version 18.0, you may see nSTATUS assert and remain low after a configuration error is detected. This behavior may be seen in all supported configuration modes other than JTAG configuration.

Workaround/Fix

If nSTATUS asserts low due to a configuration failure, drive nCONFIG low after 1.5ms and then back high to initiate reconfiguration. The nSTATUS signal will deassert to a high state to then allow reconfiguration to proceed.

This problem is scheduled to be fixed in a future release of the Intel Quartus Prime Pro software.
