Hi all, I am supposed to do the simulation of transmission lines of OC48 section. Since I am a newby to this, I dont know where to start,, what are the things needed for this, etc. The rough idea I have is to simulate it in SPICE (WinSPICE or SPICE OPUS). I would like to know, 1. Which SPICE transmission line model is to be used? How to get deduce its parameters from the PCB line parameters for the same? How differential lines are modelled in SPICE? 2. What are the analysis to be done? Will transient analysis (for rise time degradition etc) and ac Sweep analysis would suffice? The very idea I am having may be incorrect. Please guide me in this work. Thanks and Regards, Ashok. ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field 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
