how to decide the number of jobs in Run settings in generate output products

I am using Vivado and have already validated the block design. I need to generate output products and i am not sure how to decide the number of jobs in run settings there. I have attached a screenshot of the window below.

Hi @thilankathi 

 

It depends on your computer.

How many cores and threads are there ?

 

Best regards,

Hi @thilankathi 

If I don't need processing power for other applications, I typically maximize the number of jobs.


Cheers

Hi @thilankathi

Go through this AR and UG 904 to understand more about the number of Jobs and its usage. https://www.xilinx.com/support/answers/60655.html

Re: how to decide the number of jobs in Run settings in generate output products

Thanks for the replies guys. so does thid mean that the number of jobs means the number of jobs done in parallel? Is that why it depemds on the number of cores in your computer? Anyways how does it affect the performance on fpga? or it doesnt affect the performance inside fpga? I mean what depends on the number of jobs ?

Thanks in advance!

@thilankathi 

>> mean that the number of jobs means the number of jobs done in parallel? 

Check this at your end to understand it better. - Create a GUI project in Vivado - add multiple Xilinx IPs from IP catalog - now OOC pop up will come to generate its products where you will see that pop up asks to set the number of jobs - If you set 1 there then only one OOC synthesis will be done at a time. If you set more than 1 then you will see parallel OOC synthesis is happening for those IPs. You can see these in Design Runs tab.

Hope you will get your answers by doing this exercise.
