How to speedup the compilation of Quartus II

Hi, I have met a problem when I try to compile a big project. It cost more than 36 hours using the Quartus II 64-bit software, but it only complete 11% of the total compilation process. What can I do...

There are many things that can cause this:

1. Have you got a large ram thats not inferring rams and being built with logic? this will cause a HUGE slowdown.

2. Have you got enough ram? You dont specify what part it is, but the larger stratix and arria devices recommend a minumum of 48GB of ram! If it starts using the swap space/virtual ram, it can go very slow.

3. Is your PC got a big enough processor?

It usually 1 and 2 that are the biggest factors, especially 1. Given your compile Time, I suspect some dodgy code. Even full large devices should complete in <12 hours..
