Vivado 2017/2018 Max CPU Cores

I am looking to speed up my vivado projects and wanted to know the max cpu cores that vivado can utilize in the following tasks:

                [ Simulation / Systesis / Implemenation ]

for Vivado versions 2017 - 2018.

 

Also does vivado support two processors in the same PC?

Hi @afgarrido 

The default number of cores used will be 4.

You can override this parameter by :

set_param general.maxThreads <new limit>

For implementation check page no.7:

For synthesis check page no.37:

For simulation check pag no.206:

Thanks,

I see that 8 threads is the max setting for running implementation in parallel.  If I have a 24 core processor vs a 8 core processors will the implementation speed up by 3x?

Just bumping the thread to see if I could get an answer to the question stated in the previous post.
