Hi, In Hspice by Using the option GSHUNT, we can add conductance from each node to ground. Adding a small GSHUNT to each node, helps us to solve â??timestep too smallâ?? problems.Can anybody share the concept behind this..Why do we need a Gshunt and also by adding Gshunt how can we solve the â??timestep too smallâ?? problem ... Thanks in advance for the feedbacks. Have a great day. ------------------------------------------------------------------ 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 Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
