Synthesis crashes on Quartus Pro - Synthesis crashes on Quartus Pro I get crash while synthesizing a vhdl design on Quartus Pro for Stratix and Agilex FPGAs The design elaborates without any problem. Here is the crash log Tried on Quartus Pro 22.1(Windows), 22.2(Linux), 22.3(Linux) Problem Details Error: *** Fatal Error: Segment Violation: faulting address=0x18, PC=0x7f1996928e1a : 0x7f1996928e1a:

The approximate release date of 22.4 would be end of the year 2022 which means end of the Q4. Thanks, Best regards, Sheng p/s: If any answer from the community or Intel Support are helpful, please feel free to give best answer or rate 4/5 survey. Replies: Re: Synthesis crashes on Quartus Pro Hi Sheng, Could you please let me know the approximate release date of 22.4 Regards, Artak Replies: Re: Synthesis crashes on Quartus Pro Hi @Artak , From expert team, the problem is planned to be fixed in v22.4. Let me know if you have any further concern or update. Thanks, Best Regards, Sheng Replies: Re: Synthesis crashes on Quartus Pro Hi @Artak , Done reporting this issue to internal expert team. Please allow some time for investigation. Will come back to you once there is any update. Thanks, Best Regards, Sheng Replies: Re: Synthesis crashes on Quartus Pro Hi Sheng, I have sent the design files and crash reproduction instructions via email. Regards, Artak Replies: Re: Synthesis crashes on Quartus Pro Hi Artak, You can provide the sample design privately to me through this email: qi.sheng.ng@intel.com Thanks, Best Regards, Sheng Replies: Re: Synthesis crashes on Quartus Pro Hi Sheng, Could you please provide an email address or some other way to send the design to you. I would like to keep the design files private. If my understanding is correct everybody can access the files attached here. Regards, Artak Replies: Re: Synthesis crashes on Quartus Pro Hi @Artak , Could you provide a sample design file which duplicates the Fatal Error for further investigation?
