dni

Is dni not supposed to work in quartus pro 22.4?

[AEsqu]

After deleting the quartus settings (I had to do that many years ago as well):

rm -rf ~/.altera.quartus/*

Then the Quartus opens the windows to select the license,

I enter it but then it crashes.

So that does not seems to be license related.

A colleague found that the crash was due to a unsupported soft link in the wrapper,

I can start the tool now.

Quartus 23.1 pro reports a .qsf error with this line:

set_global_assignment -name ANALYZE_LATCHES_AS_SYNCHRONOUS_ELEMENTS ON

That line seems ok in Quartus 22.4 pro (Default value is on according the doc).

How are the latch being analyzed in Quartus 23.1 pro then (still with the falling edge enable analysis or as combi)?

Looks like it cannot analyse anymore as sync, I saw that warning:

Warning(335091): The Timing Analyzer found 77 latches that cannot be analyzed as synchronous elements. For more details, run the Check Timing command in the Timing Analyzer to see the list of unsupported latches.

Note : We extensively use latch for clock gating (as for the chip) and they are functional, so they cannot be removed.

Alex,

It seems like your dni problem has been solved. Can you post a new thread for the new problem you are seeing?

Thanks,

Hi Nurina,

the RTL analyzer is indeed working in Quartus 23.1 pro,

see the attached picture.

I will create two other topics for the 2 other points.
