Honored ContributorCompilation Time
Hi,
Does anybody know how to reduce the compilation time from Quartuss II and the simulation time from ModelSim. ThanksForum Discussion

Altera_ForumFor Quartus compilation time, see "Tools --> Advisors --> Compilation Time Advisor". Also see "Compilation-Time Optimization Techniques" in Chapter 8, "Area, Timing and Power Optimization," in the Quartus handbook, Volume 2, Section III

Thanks Brad.
Do you know if Quartus II supports the use of IncrediBuild (http://www.xoreax.com/main.htm). The software engineers in my company using this tool to reduce the compilation time. - Altera_Forum
I've never heard of IncrediBuild. The web site at your link talks about distributing processes across "multiple cores/processors". Quartus has this ability built in. Some parts of compilation can use up to 4 CPUs. You control this in the field labeled "Maximum processors allowed for parallel compilation" on the "Compilation Process Settings" page of the Settings dialog box. Using n processors does not reduce compilation time to 1/n, but it does help. The Quartus report tells you how much it helped.

Can you give some specifics? How long is your compile? How much time is spent in each flow (Synthesis, Fitting, etc.) The techniques you would use to reduce compile time vary greatly depending on where the bottlenecks are.
