Very long compilation time / Advanced physical optimization. Quartus Prime. Cyclone V

Dear all, I am a new user of Altera, Quartus and Cyclone V. We have a (preliminary) design that I finally managed to compile in about 3 hours. About the half of the Cyclone V (5CEBA9F31C8) is u...

Without any timing constraints, it will assume you want an FMax of 1000 Mhz, and may try rather hard.

Set up timing contraints for your design may make it's life easier.

Thank you Tricky!

Indeed, in the mean time I added some timing constraints (not all, for now) and the compilation is quite faster. My first goal was only to see if the design could fit in the FPGA (the board is not yet designed, we could still chose another FPGA...), so my project is not complete.
