I have a problem with my design. It's not too complex (~7K LE), verified by modelling, successfully compiled and assembled, but I don't have timing due to internal Quartus error.

Hi,

 

Is that fine for you to upgrade your design to the latest version 19.1lite?

 

Can you provide us the design.qar files for duplication? You may check your email on this.
