Hi,

Can you upgrade to the latest version of the Intel Quartus Prime software and see if the problem persists?

Thanks.

I try to upgrade the quartus II 15.0 to quartus II 15.02,this problem also persists.

Hi,

Can you upgrade to the latest version v19.1 standard (linux) or v18.1 (windows)?

Thanks.

Is there any other way, because I have used a lot of IP cores in my design, I need to regenerate the IP core when I upgrade to 18.1

Hi,

I could not find any related cases in our database. The only method is to upgrade the design to the latest version and see if the problem persists. If yes, kindly provide the sample test case in the latest version for investigation.

Thanks.

Hi,

May I know if you have any updates?

Thanks.

I don't have any updates,I try to modify some setting of fitter,then it's solved

Hi,

Could you share what settings fix the error so that other users can benefit from it?

Thanks.
