CPU uasge by the fitter

--- Quote Start ---

Hi

I am using quartus 9.0 . When i run qaurtus on 4 core processor , the fitter summary report that it is using only 1.6 . Thus the amout of time required to compile is 40 min. Is there a way to increase the processos usage . The option "use all processors" is also set.

Thanks

Hi Avinash,

Not all algorithms in Quartus can take advantage of multiple processors. The processor usage you get will depend on your particular circuit. In general, very large designs (those that take hours to map or fit) will see a larger relative benefit than smaller designs, though there's a lot of variation.
