I don't think my computer is slow. When altera release new device or new QII version, they always claim that performance enhance and compilation time decrease. It seems that's not the truth.

I have used ArriaGX(EP1AGX60), which size is 1/3 of EP4SGX180. But its compilation time is only about 10 minutes when using old QII version.

So i think that EP4SGX180's compilation time should be about half an hour. Though there are other resource increasing, RAM, muliplier..., but Altera claim the new QII version can decrease the compilation time. So 30 minutes should be reasonable.
