Why does the Mailbox Client Intel® FPGA IP only read 0.6V from the Intel Agilex® 7 FPGA Voltage Sensor when the VCCR_CORE is 1.2V?

Environment

    Intel® Quartus® Prime Pro Edition
BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 20.4 and earlier, you may have an incorrect voltage reported for VCCR_CORE (Channel 5 in the Intel Agilex® 7 FPGA Voltage Sensor).

This is because the value is not doubled correctly. 

 

 

Resolution

To work around this problem, manually double the reported voltage value.

This problem is fixed starting with the Intel Quartus Prime Pro Edition Software version 21.1.
