Dear Bala, >>> ... I can calculate RLC in frequency domain using Sigrity tool, however it >>> will take decoupling capacitor also into account... <<< That is true only if you setup the simulation that way... I'm speaking without having any knowledge of your structure but Cadence Allegro Sigrity has both Hybrid and Full 3D EM field solvers to extract component level parasitics and have the capability to extract RLGC from the resulting S-parameters. Please contact me offline and perhaps I can help you further. Thank you.

I checked with many CAD tool vendor and no tool support this feature. I can get parasitic of my trace alone from cadence. But I need combined (trace+pad+via) parasitic capacitance. Please help -- bala ------------------------------------------------------------------ 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
