Hi all I am designing a ring oscillator , my problem is that the output frequency of a practical ring oscillator may vary(say +/-5 % around the expected freq) i.e i have to get afreq vs time plot to measure jitter, settling time etc.But using Hspice i dont know how can i find the freq which may change with time.The time period may differ from one cycle to the next in the output, so i have to measure the period for every consecutive cycle for about 1000 cycles.the only way i got to know is using 1000 .measure statements. however i wish to know if there is abetter way of doing this? Thanks &Regards K.Navaram Kumar ------------------------------------------------------------------ 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 technical documents are available at: http://www.si-list.net List archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
