Hello,
I've been trying to run pnoise analysis on my circuit. During PSS
analysis, after running for a while and failing to converge, I get the
above message and then PSS usually converges.
I have followed the suggestion from spectre and adjusted tstab several
times in my testbench but each time the story repeats. Spectre fails to
coverge, adjusts tstab itself and then converges.
Therefore, my question is: how can I get more information about what
EXACTLY spectre does during this "adjust tstab" phase so that I can
include these options in my test bench and not waste time during my
next simulation.
Thank you for your replies.
Regards,
Robert
