The Quartus Prime Software quit unexpectedly

[GD76]

Running Quartus Standard Edition 18.1 (cannot upgrade). Always had no issue in the past but recently keep getting the message "The Quartus Prime software quit unexpectedly" whenever "Start Compilation" clicked. The design did not change.

The error is

Internal Error: Sub-system: SDR, File: /quartus/sld/sdr/sdr_data_session.cpp, Line: 2089
Unexpected FIO_FILE_SYSTEM::status() return

Not sure what to fix.

Ganesan,

To me this is directly a bug since the error message is internal error.

Is it possible to attach the qar of the design or small design that replicate the issue?

You can send the design privately via private chat if the design is confidential or email.

How to send it through email or private chat?

What is the operating system?

Have there been recent updates installed?

Did it stop working after some recent update?

Maybe back out recent updates and pause updates to debug the issue.

That is an older version of Quartus and recent system updates may be incompatible.

Running 18.1 for almost 9 months on Windows 10. No updates done.

What I discovered is (not solution yet), removing the signal tap file and deleting the "filename.cmp.rdb", then compilation works without the Quartus quitting unexpectedly.

The signal tap files worked for a week so. No change made. So not sure why yet.

I sent an email to you and can reply and attach the design there or via private message ( I have sent to you).

Let me know if you did not receive any of those.

After removing the signal tap file from project, deleting the project.cmp.rdb file, I recreated a NEW the signal tap file. Now I can compile. Not sure why the previous STP file is the issue. It was working for a long time.

Hi Ganesan,

Glad you had found the workaround for this.

The example design from you might be good test case for Quartus enhancement, thus hopefully you able to provide that.

Otherwise let me know if there is any other concern.
