I am facing convergence issues while doing transient analysis on a LC MOS cross-coupled oscillator.
Spectre Version : 10.1.0.204
As suggested by Andrew on this forum, I am doing moderate analysis with integration method : traponly
For inductors of value 1.59nH and Capacitors of value 15.9nF, oscillator is working fine(oscillating at 1MHz). When I change these values to 1.767nH and 17.67pF, it is throwing convergence errors as mentioned in the attached file. I will be glad if someone can help me to find the solution.
