Title: Newton: No convergence at time . ..  transient convergence help Post by jiesteve on Aug 26th, 2008, 4:48pm Anybody have any suggestions for the following non-convergence errors?  It only appears to be happening at certain corners at 100C.  Node X is a high-impedence node (floating).  I am running eldo and have tried playing around with the TUNING setting.  Seems to work at STANDARD accuracy but I need higher accuracy.  Any suggestions appreciated. ---- Newton: No convergence at time :0.259943Nano ; try to pass over...  pb on or around node X TIME 2.609432e-10: end of non-convergence points Newton: No convergence at time :0.263943Nano ; try to pass over...  pb on or around node Y TIME 2.649432e-10: end of non-convergence points Newton: No convergence at time :0.269943Nano ; try to pass over...  pb on or around node X
