Due to a problem in the Quartus® Prime software version 17.0 and earlier, you may see intermittent M20K write failures in your Arria® 10 design.
The failures are characterized by
- Intermittent failures to write a zero
- Failures are not timing dependant
- Higher Vcc increases the rate of failures
- Higher temperature increases the rate of failures
This problem is fixed beginning with the Quartus® Prime Pro and Standard edition version 17.1
