About conversion of large pads

Question asked by mjk on Dec 22, 2017

Dear all,

 

I have a question about conversion of large pads.

 

When I run PI simulation or export to pdn editor, I can see the "Convert Large Pads into Area" dialog box.

 

 

I compared the z-parameters of the PDN with and without conversion to understand this function.

But I found out that there was no difference.

 

Could anyone explain me about this function?

I'd also like to know about difference between  the results (e.g. dc drop, z-parameter and ffs file) with and without conversion.

 

Thank you.
