My board is designed to operate ADCs and DACs of 16bit at 250 MHz range for generic application (My board also includes FPGAs and other devices for data storage and retreival operations). Now I would like to do PI simulations to my board to find out if everything is alright. The following are some of the questions I have: 1) Attached are the results of decoupling wizard through lumped analysis. I am simulating for 1.2V power plane and would like to know if I need to add any decoupling capacitors. Can you guide me looking at the results what I need to do? Do I need to take care of those antiresonant peaks (@ around 5 MHz)? Do I need to suppress them? Could you direct me to literature on this topic? 2) How to selected AC power pin model ? How to practically select the signal type and shape for an application. Can you give me any example or driect me to some sources? 3) How do I select the maximum frequency for control frequency sweep in decoupling wizard? (How do I find the bandwidth for my generic application?) 4) Is there any benchmark design available from hyperlynx with which I can learn PDN analysis at a good detail? Any help on to my questions or additional inputs on this topic are highly appriciated. Thanking you in advance, Ravi ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List forum is accessible at: http://tech.groups.yahoo.com/group/si-list List archives are viewable at: //www.freelists.org/archives/si-list Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List forum is accessible at: http://tech.groups.yahoo.com/group/si-list List archives are viewable at: //www.freelists.org/archives/si-list Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
