IODELAY application

Hi,

 

May anyone please explain what an IDELAY/ODELAY is? Where this primitive is used?

And where can I find simple examples of this primitive to learn its usage?

 

Thanks

Hi @mo69_hoseini

 

If you are using 7 series, refer this link below:

If you are using Ultrascale, refer the link:

I think you will get sufficient information in these doc.

 

Regards

Rohit

Re: IODELAY application

Hi @thakurr

 

In my book, the user guides are not suitable for beginners and it seems they are written for skilled designers who need to know how to use new technologies

 

I need something simpler. I know IODELAY is used for delaying inputs or outputs, but I don't know where they are necessary. Could you please give some practical and simple examples?

 

Regards
