I can't share my project, so, I understand your inability to help me with this problem. Anyway, thanks for your replies, Best regards, Re: Final postfit netlist check failed ; Internal Error: Sub-system: FDRGN Hi, Thanks for your help Unfortunately, I'm not authorised to share my project. To complete the compilation, I had to delete DDR4 communication with FPGA. This issue can be solve from your side with this modification. Best regards, Re: Final postfit netlist check failed ; Internal Error: Sub-system: FDRGN Thanks for your reply, Unfortunately, I can't update my Quartus version because of project traceability.

I didn't made any modification, and I can't explain it. Thanks for your support, Vincent Re: Error(11176): quartus\bin64\ccl_ver_jni_stub.dll: Can't find dependent libraries Hi @RichardTanSY_Altera Unfortunately, I can't share any project because of industrial copyright. But I don't think this error occur in a particular project. Maybe, this a consequence for using Platform Designer (or directly qsys) Thanks for your help, Vincent Re: Error(11176): quartus\bin64\ccl_ver_jni_stub.dll: Can't find dependent libraries Hi @RichardTanSY_Altera I reuse this part of code for SFP+ driving and JTAG debugging. These two blocs are present on several project, and all of them generate the same error. Best Regards, Vincent Re: Error(11176): quartus\bin64\ccl_ver_jni_stub.dll: Can't find dependent libraries Hi @RichardTanSY_Altera I downgrade Quartus Prime Pro to 19.1 and IP generation for the debug fabric is done correctly Unfortunately, the problem remains in version 19.4 and 21.2 Best Regards, Vincent Re: Error(11176): quartus\bin64\ccl_ver_jni_stub.dll: Can't find dependent libraries Hi @RichardTanSY_Altera Unfortunately, I can't upgrade to Windows 10 version because my computer is for professionnal purpose.
