I am building a variant of a working project, using Quartus Prime Lite.
It fails Analysis & Synthesis right at the end (97%).
I have tried in V17.1.0 and 18.1, same error with both.
It occurred after I modified an Avalon FIFO memory component in my qsys system.
When I compare the sdc file from this project with my earlier successful project, only the project names (my_proj) are different.
Any Ideas/workarounds?
Thanks John.

Does your project use any DCFIFO IP blocks, If so delete the component, create a new instance and try building it again.

Hello,
Sometimes you need to clean your project + delete all generated files before recompiling.
A mixup can occur where the quartus menu command "project/clean" is an option or even manually delete automatically generated subdirectories.
(I had it before that the output of 2 qsys generations with small modifications between 2 versions mixed things up. Cleaning things up got me back on track.)
Best Regards,
Johi.

Hi John,
Try to recompile by deleting the 'db' & 'incremental_db' folder from project generated directory.
Let me know if this has helped resolve the issue you are facing or if you need any further assistance.
Best Regards

Hi Vikas,
Deleting DB & Incremental_db folders did not fix the issue.
Thankfully Abe's suggestion of deleting the DC-FIFO component and creating a new one did fix it.
Thanks to everyone for the helpful suggestions.
John.
