Compiling with Quartus using LPM_DIV with Pipeline is better
http://www.alteraforum.com/forum/attachment.php?attachmentid=11715&stc=1 I have too low frequency but during fitting I have hibernated PC and when resumed today compilation time was wrong (counted also when pc was turned off) and then skipped some optimizations..
Info (170236): Routing optimizations have been running for 12 hour(s)
Info (170242): 197139 out of 213944 signals have been routed.
Info (170238): 27703 interconnect resources are used by multiple signals.
Info (170199): The Fitter performed an Auto Fit compilation. Optimizations were skipped to reduce compilation time.
Info (170200): Optimizations that may affect the design's timing were skipped
Never hibernate during compilation..
PS: Powerplay report that Routing Dynamic Power is more than Block Thermal Power, routing power is used only at configuration?
