Title: Ring oscillator on ELDO RF
Post by David Levacq on Nov 29^th, 2002, 1:46am

I'm trying to make a steady state analysis of a ring oscillator on ELDO RF (.SST OSCIL analysis). Unfortunately, I cannot get any convergence. I tried to increase the number of harmonics and to activate the options "sst_convergence_help=continuation" and increased the maximum number of iterations up to 200, without success. What can I do? Thank you...

where did you put the probe?This this problem can occur when desiner put the probe on the buffer instead of on one of the delay stages nodes.
