On-die capacitor and package parasitic for Cyclone V

Hi,

Perhaps you can try to check on the Power Delivery Network (PDN) tool for Cyclone V Device. You need to download the zip file in the link below and open the spreadsheet. You can go to System_Decap tab and change the device family accordingly.

Hi Aqid,

Thank you for this reply.

This is a very good tool to provide idea of PDN.

However, I am specifically looking for some information on decap value connected between BGA ball to die of the IC.

a small decoupling capacitor that we place inside IC package or a parasitic effect due to this

I am looking for IC power pin model to avoid Target impedance issues on frequencies beyond 200MHz

Hi,
where did you get the idea that Cylone V has internal bypass capacitors? I'm no aware of an Intel document mentioning it. I doubt that there's room for capacitors in BGA package.

Hi,

I also not sure if we have disclosed this information. So far, the only I can provide is the information that was included in the PDN as suggested earlier.
