Quartus crashes - Quartus crashes I am using Quartus Prime 23.2.0 Build 94 06/14/2023 SC Pro Edition. Running on Ubuntu 22.04.3 LTS I have attached the dummy project during which the Fitter crashes. I have also tried other projects (including example design from Intel) with the same result. It seems from the attached dump file that Quartus is looking for a file that does not exist. In fact the entire directory called "20nm" does not exist. I would appreciate any leads on solving this problem. Replies: Re: Quartus crashes Hi David, Noted. You may use it as temp workaround. Let me know if there is any concern. I will take a look into the design Replies: Re: Quartus crashes Hi SyafieqS, 1. I attached all files to my original post. Now on vacation for 10 days without access to my work PC. 2. After my posting I found other people reported EXACTLY the same problem - so it is definitely a bug in Quartus. 3. I downgraded to an older version of Quartus and everything is working OK - further supporting my claim that the newest version is buggy.
