Quartus Compilation took 4 hrs

[Altera_Forum]

Hi all,  

 I am compiling a sample AES program from the book Design Recipes for FPGAs by Peter Wilson.   However, it took four hours to compile the two files. Here's the message from Quartus II: Info: Started Full Compilation at Mon Oct 26 16:11:22 2009 Malay Peninsula Standard Time Info: Ended Full Compilation at Mon Oct 26 20:27:12 2009 Malay Peninsula Standard Time  The example given use a package approach with a suite of VHDL functions rather than the structural approach.   Can any one suggest a faster setting for compilation?  Cheers, Dennis

you didn't say anything about your target FPGA and the pc you run Quartus. Does this pc have enough memory or is it swaping ? also you didn't mention how you have setup your project. 

What Quartus Version do you have ? Maybe the meneu Tools -> Advisors -> Compilation Time Advisors may help you

I am running Quartus 9.0 sp2 on a WinXP SP3 with Core 2 Dual Processor with 4GB Ram.  

 Will take a look at the Compilation Time Advisors and feedback later.   Thanks.

Open You Quartus Project 

Menue Assignments -> Settings  Compilation Process Settings choose Parallel compilation . Use all available processors enable Use smart compilation  Fitter Settings Set fitter effort to Auto Fit   your system should be fast enough a Cyclone II EP2C70 design with ~70% usage is compiled here on a E8500 cpu within 50 minutes. Is your project stored localy or via network ?
