It looks like there is some issue with the blank check. I will feedback this to the engineering team and see if we could fixed it in the future Quartus released.

Hi John,

We have come to the same conclusion that the Blank check is not reliable and is not necessary and can be removed from the production test process. However, it would be helpful at some point to have Intel confirm the issue and perhaps let us know if a new version of the tool becomes available with that fixed.

One other note is that we have transitioned from the EPC4ASI8N to the EPCQ4ASI8N version of the memory device since the original non 'Q' version of the part is no longer made.
