Hello everyone, I am doing the timing analysis of Ethernet MAC RGMII interface. But confused to calculate the setup margin and hold margin. In the timing specification of driver, its not clearly mentioned about the setup and hold time/ Please guide me on how to calculate the setup and hold time for the given timing specification. TskewT -> -500ps to +500ps TskewR -> 1ns to 2.6ns Tclk -> 7.2ns to 8.8ns... Typ 8ns Tr/Tf -> 0.75ns Max Thanking you in advance, Shrishail ------------------------------------------------------------------ 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
