Hi,
Internal message as below:
There was a Quartus Prime Pro issue broadly discovered by customers, field and internal teams in which the Quartus code that calculates the date and time from the DDM client ID mistakenly identifies the time being shifted an hour from the current time which in turn, causes a Quartus crash to take place. This issue began when the year turned to 2026 and we moved to a two-digit date in the month of January. This crash affects:
Quartus Prime Pro Software versions v23.3 through v25.3.1
Quartus Embedded Edition v25.3 and v25.3.1
Quartus Programmer v23.3 through v25.3.1
This issue can be seen when using Quartus software through command line or GUI interface.
Quartus Patch requests have been filed for the above software and tools. A KDB draft is available and will be reviewed and released when the patches are ready. These fixes and KDB are being driven with utmost priority.
Will get back once the patch and kdb are available.
