Quartus Prime software (18.1) quit unexpectedly

Dear Sir/Madame, When building a project in quartus 2018.1 the GUI stops (32% of the fitter progress) and the message in the subject pops up. The report is below. Do you have any idea of what can be...

    The "99.64% utilization..." statement was based on the 2019 design.

    The person who contacted Intel at that time was named Nathanael Huffman.

    I have also attached the 2019 design for your reference.

    Based on this information, my takeaway point is that the .INI file, provided in my previous reply, is derived from the 2019 design and should be safe to use in your current project. It has previously been verified by the engineering team in 2019.

    Best Regards,

Wait a sec, I have found in the database that the design reviewed is indeed the same as yours. It was filed in the IPS case back in 2019. Does that ring a bell? It seems that some information may have been lost or overlooked over time.


Regarding what the issue was, I quoting what the engineering saying directly:

"When the clustering is computing utilization on a converged clustering solution, it sees a 99.64% utilization on the full chip. This is less than 100%, so there should be no over-utilization; However, the code assume that anything < 1.0 (eps=0.01) as the rule to filter out over-utilization regions, so that means any regions with >99% utilization counts as overflow and lead to bad things downstream. "


Last time, the engineering team confirmed that this issue does not exist in the Quartus Pro v19.1. Therefore, you may consider upgrading your design to Pro, which will provide you with peace of mind.


Best Regards,
