When using the Intel® Quartus® Prime Pro Edition Software version 18.0, if the SmartVID (-V) graded Intel® Stratix® 10 device is configured in PMBus slave mode, the Intel® Stratix® 10 device will not respond to any PMBus commands during the Partial Reconfiguration process. If the master power management controller queries the Intel Stratix 10 device for a voltage update during Partial Reconfiguration, the Intel Stratix 10 device will not respond.
After the Partial Reconfiguration process is complete, the Intel Stratix 10 device will respond to the queries again. The master power management controller needs to re-issue the queries until it gets a response.
