Quartus Prime software quit unexpectedly during Analysis & Synthesis

Hi all, I tried to run analysis & synthesis on a rather large design on Quartus Prime Pro 21.2, and got a popup saying "Sorry! The Quartus Prime software quit unexpectedly." The following is the...

Btw, may I know how long do you run the Analysis and synthesis with your design?

For my case, it never stops running after 1 day until I force stop it and the IE pop up.

Hi Richard,

The error message popped up around 2 hours after Analysis & Synthesis started.

Also, I think I found the problem.

  • When instantiating a one-word 512-bit 2-port RAM, it takes around 13 M20K block memory instead of just one, which makes the memory usage of the device on which Quartus is running increase dramatically and finally causes the error and fails the compilation. (PS: I instantiated around 400 512-bit 2-port RAM, which might take 400*13 block memory for Quartus to synthesize)

After some architecture transformation on 2-port RAM, I was able to compile the design properly.

Thanks.

Joseph
